How can I create an alias for a generic class in C#?

Question

How can I do the following in C#? What is the right way to write the first line of this code snippet?

using KVP<K, V> = System.Collections.Generic.KeyValuePair<K, V>;  class C { KVP<int, string> x; } 

Answer 1

You can't, basically. You can only use fixed aliases, such as:

using Foo = System.Collections.Generic.KeyValuePair<int, string>;  class C { Foo x; } 

Answer 2

In some cases you can go with inheritance:

public class MyList<T1, T2> : List<Tuple<IEnumerable<HashSet<T1>>, IComparable<T2>>> { }  public void Meth() {     var x = new MyList<int, bool>(); } 

Though not in your particular case, as KeyValuePair is sealed :-(
