Vista - Non Virtual method using CodeMemberMethod -- CodeDOM

I am using CodeDOM namespace to dynamically generate code in C#. But when I
am creating method using “CodeMemberMethod� then its creating a virtual
method even though I am not specifying anything to create a virtual method. I
am using following code to add method:

CodeMemberMethod testMethod = new CodeMemberMethod();
testMethod.Name = "testMethod";
testMethod.Attributes = MemberAttributes.Public;
testMethod.Statements.Add(new CodeSnippetStatement("//TODO: Code goes
here....."));
testClassType.Members.Add(testMethod);

Question: How to create method without Virtual keyword?
