Generate TestCases for Methods based on its Signature using CodeDom in C#

Question

Consider the following Code snippet,


Assembly asm = Assembly.LoadFile(DLL_Path);
Type t = asm.GetType(DLL_NameSpace.MyClass, false, true);
clsMethodInvoke mi = new clsMethodInvoke();
foreach (MemberInfo oMember in t.GetMembers(mi.GetFilter()))
{
//code here
}

These are the values in the follwing variables,

t = {Name = "Class1" FullName = "a.Class1"}
oMember = {Int32 add(Int32, Int32)}

Now from these values i need to Generate NUnit based TestCases as follows,

[Test()]
public virtual void Testadd1() {
Class1 Class1 = new Class1();

int a = -1; //random values are stored here
int b = 2147483647; //random values are stored here

}

So having the type of the Class in an Assembly i want to generate test cases for each method, as show above. How can i generate such Test Cases.?
