c# - How can you get the names of method parameters?

Question

If I have a method such as:

public void MyMethod(int arg1, string arg2)

How would I go about getting the actual names of the arguments? I can't seem to find anything in the MethodInfo which will actually give me the name of the parameter.

I would like to write a method which looks like this:

public static string GetParamName(MethodInfo method, int index)

So if I called this method with:

string name = GetParamName(MyMethod, 0)

it would return "arg1". Is this possible?

Answer 1

public static string GetParamName(System.Reflection.MethodInfo method, int index)
{
    string retVal = string.Empty;

    if (method != null && method.GetParameters().Length > index)
        retVal = method.GetParameters()[index].Name;


    return retVal;
}

The above sample should do what you need.
