default value for generic type in c# [duplicate]

The docs for Dictionary.TryGetValue say:

When this method returns, [the value argument] contains the value associated with the specified key, if the key is found; otherwise, the default value for the type of the value parameter. This parameter is passed uninitialized.

I need to mimic this in my class. How do I find the default value for type T?

How can this question be modified to make it show up in the search?

Exact duplicate of Returning a default value. (C#)

You are looking for this:

default(T);

so:

public T Foo<T>(T Bar)
{
   return default(T);
}

default(T);

Using the default keyword:

T t = default(T)
