Generate .Net class from XSD with references to other XSD using xsd.exe

Posted on


I’m currently using a modelling tool for the application design, and below is an example of how we have 2 entities, which in the end will produce 2 xsd files, Transaction.xsd and Person.xsd.

schema

Notice in the Transaction.xsd below, there is a madeBy element with the type of Person which is declared in another Person.xsd (xs:import)

xsd

Now, if we want to generate the Transaction.xsd, it will give us

C:\Schema>xsd.exe Transaction.xsd /c
Microsoft (R) Xml Schemas/DataTypes support utility
[Microsoft (R) .NET Framework, Version 2.0.50727.1432]
Copyright (C) Microsoft Corporation. All rights reserved.
Schema validation warning: Type 'https://bembengarifin.wordpress.com/Person:Person' is not declared. Line 8, position 5.
Warning: Schema could not be validated. Class generation may fail or may produce incorrect results.
Error: Error generating classes for schema 'Transaction'.
- The datatype 'https://bembengarifin.wordpress.com/Person:Person' is missing.
If you would like more help, please type "xsd /?".

So how to resolve that is to use


C:\Schema>xsd.exe Person.xsd Transaction.xsd /c
Microsoft (R) Xml Schemas/DataTypes support utility
[Microsoft (R) .NET Framework, Version 2.0.50727.1432]
Copyright (C) Microsoft Corporation. All rights reserved.
Writing file 'C:\Schema\Person_Transaction.cs'.

Note: You will need to put the referenced xsd prior to the xsd which is having the references, or else it will throw the same error.

Hope this helps ;)

    Dear Bembeng Arifin

    Great Post. Sir, i have an .XSD file which itself contains reference to so many other .XSD files. In your case, you have only 1 reference to another .XSD file so by putting Person.XSD in front of Transaction.XSD might solve the issue but how can i solve my issue with so many references to other .XSD files

    I tried using WSDL tool to generate the code from Contract-First WSDL provided by a company. This WSDL contains references to other .XSD files so i thought WSDL tool will generate the complete code but it threw error. No code was generated

    Can you please help me?

    Thanks

      Hi Vikas,

      You should be able to generate the XSDs, as long as you put the referenced xsd prior to the xsd which is using it.
      For example.
      – A.xsd has an import reference to B.xsd
      – B.xsd has an import reference to C.xsd

      you can try : xsd.exe C.xsd B.xsd A.xsd
      hope this helps

    Dear Bembeng Arifin

    I have an WSDL file which contains reference to XSD files. I want to run a tool against WSDL file not against XSD file. I thought the tool will pick up WSDL file and its related XSD files and will generate server side code

    Thanks

    If you start the code generation from a web service you do the same with wsdl.exe instead of xed.exe.

    wsdl.exe MyService.wsdl MySchema1.xsd MyReferencedSchema2.xsd MyReferencedSchema3.xsd …

    Hey,

    thats great post but there is a small problem when you run it you get 1 class instead of 2 classes. Ok you may say what is the matter with that? I give you a scenario below.
    there are 2 root xsds and 3 reference xsds
    root: xsd 1 xsd 2 references: xsd A xsd B xsd C
    1 has references A,B,C
    2 has references A,B,C

    when you create classes using the way you illustrated you end up with 2 class both having same properties (property definitions of A,B and C). then if you try to create a WSDL using these 2 classes, Visual Studio will warn you by saying multiple property declarations. Therefore you need to separate them in a common/shared classes again. thats a tired way of doing if you have too many xsds with same references combined.
    ok, now the question is “is there anyway I can accoplish 2+3 classes generated rather than 2 classes for the scenario above?” I know some 3rd party programs doing that but they do sometimes wrong classes. good program suggestion will be appreciated too.

    thanks.

    Below command works for creating single file from multiple xsd referring each other.

    C:\Schema>xsd.exe Person.xsd Transaction.xsd /c

    Many thanks :-)
