Custom attribute declaration for methods

I am using CodeDom to generate a class which include some methods. I was able to declare an attribute for my methods to look similar as what Pex does when it creates a parameterized unit test:

[PexMethod]
public void myMethod()

However I would like to include something more to it like:

[PexMethod (Max Branches = 1000)]
public void myMethod()

But I am not able to include the ((Max Branches = 1000)). Could you somebody help me a bit?

    CodeAttributeArgument codeAttr = new CodeAttributeArgument(new CodePrimitiveExpression("Max Branches = 1000"));
     CodeAttributeDeclaration codeAttrDecl = new CodeAttributeDeclaration("PexMethod",codeAttr);

 mymethod.CustomAttributes.Add(codeAttrDecl);

I'm not sure what your problem is, but you can simply set the Value property on CodeAttributeArgument:

var method =
    new CodeMemberMethod
    {
        Name = "MyMethod",
        CustomAttributes =
        {
            new CodeAttributeDeclaration
            {
                Name = "PexMethod",
                Arguments =
                {
                    new CodeAttributeArgument
                    {
                        Name = "MaxBranches",
                        Value = new CodePrimitiveExpression(1000)
                    }
                }
            }
        }
    };

The MaxBranches property is on a base class (PexSettingsAttributeBase). That may be why you are having trouble. You may be reflecting over the wrong type to find the PropertyInfo to set.

You can't have spaces in the attribute values, they are just wrappers around public properties in your custom attributes class. For example:

public class TestAttribute : Attribute
{
    public bool Enabled { get; set; }
}

And you can use this like this

[TestAttribute(Enabled = true)]
void Foo(){}

So since the attribute maps to a property it has to follow normal syntactical naming rules.
