Hi all,
I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem.
I am wanting to pass a generic class in and call a method from that class. So, my code looks as such:
public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper
{
Type foo = Type.GetType(sender.GetType().ToString());
object[] userParameters = new object[2];
userParameters[0] = x;
userParameters[1] = y;
sender = new T(); //This was to see if I could solve my exception problem
MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass");
populateMethod.Invoke(sender, userParameters);
}
Exception thrown: "Object reference not set to an instance of an object."
Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!
