Not a lot of people are familiar with the xsd.exe that ships with Visual Studio. It allows you to create XML/classes from XML/classes. The following are the 4.0 xsd.exe capabilities: XDR to XSD Generates an XML schema from an XML-Data-Reduced schema file. XDR is an early XML-based schema format. XML to XSD Generates an XML schema from an XML file. XSD to DataSet Generates common language runtime DataSet classes from an XSD schema file.
Dec 14, 2008 create XSD FROM XML in C#. I've tried to do this by using the XSD.EXE.I'm sending a command to command prompt through C# code.But I'm unable to get in.
The generated classes provide a rich object model for regular XML data. XSD to Classes Generates runtime classes from an XSD schema file. The generated classes can be used in conjunction with System.Xml.Serialization.XmlSerializer to read and write XML code that follows the schema.
Classes to XSD Generates an XML schema from a type or types in a runtime assembly file. The generated schema defines the XML format used by System.Xml.Serialization.XmlSerializer.

It I’m a big fan of using xml schemas (XSDs) to generate classes that can be used to serialize and deserialize objects to and from XML (the XSD to Classes functionality listed above). If your schema changes, just rerunning xsd.exe for the correct schema updates the classes. No manually changes have to be made, including serialization code.
This Frustrates me to no end, not knowing how to solve the problem myself, and the fact that I can't finish my Near-complete game >=l EDIT: HUZZAH! I've looked online and there are a few 'Free' Window's registry cleaners, but every one I download asks me to register, and when I try to nothing happens. I might of figured it out. Level editor geometry dash. A- My computer cannot collect all the files from the download, so only the icon from shows up, but not the start up files. The error has something to do with my 'Window's registry' becoming clogged, So far It's only happened to SMBX, but I fear my other programs are in danger.
It’s a beautiful thing. The problem has been, how do you set up your classes to automatically recompile with changes to the schema, and how do you deal with schemas that import other schemas? XSDs Importing other XSDs A common issue that developers of XSDs run into is violating the DRY principle repeatedly with XSD types. For example, let’s say you create a calendar meeting request service that has two XSDs, one for the request XML and one for the response XML.
You’ve defined a xs:complexType “Meeting” that includes the date and location: But you want to use it in both the request and the response XML. You could just copy and past it into both XSD files, and it will validate just fine, but if you use xsd.exe to generate your classes, it’s going to create two classes of type Meeting, which will cause a compiler error. You could have a separate namespace for each class, but then you’re definitely violating DRY.
The answer is to place the Meeting type in a separate XSD and then reference it from both your request and your response XSD. This results in the XSDs below. C: Solution Project Types.xsd. C: Solution Project Request.xsd C: Solution Project Response.xsd Now we’ve defined our Meeting type in one file, and reused it in both our Request.xsd and Response.xsd. Getting xsd.exe To Import XSDs Now that the type has been defined in another file, the xsd.exe will generate this error if you attempt to create the create the Request XML: C: Solution Projectxsd.exe Request.xsd /c Schema validation warning: Type ' is not declared.
Warning: Schema could not be validated. Class generation may fail or may produce incorrect results. Error: Error generating classes for schema 'C: Solution Projects Request'. The datatype ' is missing.
If you would like more help, please type 'xsd /?' This is due to the fact that the xsd.exe does not use the schemaLocation hint to find the imported schema.
You’ve got to include it as a parameter. In your xsd.exe call: C: Solution Projectxsd.exe Types.xsd Request.xsd /c This will generate one file call Request.cs that has a Request class, and a Meeting class. Now we just need to create the Response class and we’re good to go. But wait running “C: Solution Projectxsd.exe Types.xsd Response.xsd /c” will create a different file, Response.cs, that contains a Response class and a duplicate Meeting class. Now we’re stuck with another compiler error and no longer DRY.
Getting xsd.exe To Not Create Duplicate Classes This is a simple fix, but it took me a long time to figure out. You have to use xsd.exe to compile all of your classes at once, so rather than running two separate commands, you just need to run one: C: Solution Projectxsd.exe Types.xsd Request.xsd Response.xsd /c Now you have one file, Response.xsd, with all three classes in it. Getting Visual Studio 2010 To Auto Recompile XSD Generated Classes Using the Project Build Events, you can set the project to always recompile the XSD classes each time you build the project. It is also helpful to rename the file so it isn’t always the name of the last XSD file passed to xsd.exe. Here are the Pre-build event command line values required to auto build the XSD classes and rename the file to XsdGeneratedClasses.cs: EDIT suggested by instead of the Registry hack (it worked back in the day for me, don't know if it still does), he suggests using '$(TargetFrameworkSDKToolsDirectory)xsd.exe' to find the path of the xsd.exe. Thanks Jamie! '$(Registry:HKEYLOCALMACHINE SOFTWARE Microsoft Microsoft SDKs Windows v7.0A @InstallationFolder) bin NETFX 4.0 Tools xsd.exe' '$(ProjectDir)Request.xsd' '$(ProjectDir)Response.xsd' '$(ProjectDir)Types.xsd' /c /o:'$(ProjectDir)' move '$(ProjectDir)Types.cs' '$(ProjectDir)XsdGeneratedClasses.cs' Now whenever the project get’s built, the XSD generated classes will always be rewritten by xsd.exe Extending XSD Generated Classes Don’t forget that classes created by xsd.exe are all partial classes.
It’s a good idea to add default constructors and logic in a separate partial class in a different file. It’s especially helpful for initializing arrays since xsd.exe generated classes use arrays and not ArrayLists or Generic Lists.
This allows you to add logic, that won’t be changed when the class is regenerated. Serializing/Deserializing XSD Generated Classes. In the 'Getting Visual Studio 2010 To Auto Recompile XSD Generated Classes', hard-coding the regpath to get xsd.exe's path is bad juju. Better to use $(TargetFrameworkSDKToolsDirectory). Below is how I accomplish this in my csproj. I'll change open to ' and close to ' since this post insists on treating this as html. Also, you have to encode the quotes around the xsd.exe command, but again, they're just shown as quotes in this post.

How to: Use the XML Schema Definition Tool to Generate Classes and XML Schema Documents. 2 minutes to read. Contributors.
In this article The XML Schema Definition tool (Xsd.exe) allows you to generate an XML schema that describes a class or to generate the class defined by an XML schema. The following procedures show how to perform these operations. To generate classes that conform to a specific schema. Open a command prompt. Pass the XML Schema as an argument to the XML Schema Definition tool, which creates a set of classes that are precisely matched to the XML Schema, for example: xsd mySchema.xsd The tool can only process schemas that reference the World Wide Web Consortium XML specification of March 16, 2001. In other words, the XML Schema namespace must be ' as shown in the following example. Modify the classes with methods, properties, or fields, as necessary.
For more information about modifying a class with attributes, see and. It is often useful to examine the schema of the XML stream that is generated when instances of a class (or classes) are serialized. For example, you might publish your schema for others to use, or you might compare it to a schema with which you are trying to achieve conformity. To generate an XML Schema document from a set of classes.
Compile the class or classes into a DLL. Open a command prompt. Pass the DLL as an argument to Xsd.exe, for example: xsd MyFile.dll The schema (or schemas) will be written, beginning with the name 'schema0.xsd'.
