how to create an interface method with CodeDom

Question

I am using CodeDom to generate my WCF service interfaces and implementation files. I cannot find any options on CodeMemberMethod that will allow me to generate an interface method. If I use MemberAttributes.Abstract I am almost there but it includes the abstract keyword which is invalid for an interface. Does anyone know the correct syntax to generate the method? Here is the code I have developed to generate the interface file: ``` private void CreateServiceContractFile(Type entity, BoElement bo, DirectoryInfo serviceOutputDir, AppParameters appPrams) { CodeCompileUnit serviceFileUnit = new CodeCompileUnit(); CodeNamespace importNameSpace = new CodeNamespace(""); importNameSpace.Imports.Add(new CodeNamespaceImport("System")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Collections.Generic")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Linq")); importNameSpace.Imports.Add(new CodeNamespaceImport("System.Runtime.Serialization")); importNameSpace.Imports.…

Accepted Answer

AFAIK, you do not have to specify any special attributes for an interface method. The following sample

```
var compUnit = new CodeCompileUnit();
var ns = new CodeNamespace("TestNamespace");
var iface = new CodeTypeDeclaration("ITest");
iface.IsInterface = true;
var mth = new CodeMemberMethod();
mth.Name = "DoSomething";
mth.ReturnType = new CodeTypeReference(typeof(string));
mth.Parameters.Add(new CodeParameterDeclarationExpression(typeof(int), "x"));
iface.Members.Add(mth);
ns.Types.Add(iface);
compUnit.Namespaces.Add(ns);
var csProv = new CSharpCodeProvider();
using (var tw = File.CreateText(@"test.cs"))
{
    var options = new CodeGeneratorOptions();
    csProv.GenerateCodeFromCompileUnit(compUnit, tw, options);
    tw.Flush();
}
```

Generates the following, valid output:

```
namespace TestNamespace {

public interface ITest {

string DoSomething(int x);
    }
}
```
