    copied!<p>Short answer, you can't.</p> <p>Long answer, you can cheat:</p> <pre><code>public class Example { internal static class Support { private delegate bool GenericParser&lt;T&gt;(string s, out T o); private static Dictionary&lt;Type, object&gt; parsers = MakeStandardParsers(); private static Dictionary&lt;Type, object&gt; MakeStandardParsers() { Dictionary&lt;Type, object&gt; d = new Dictionary&lt;Type, object&gt;(); // You need to add an entry for every type you want to cope with. d[typeof(int)] = new GenericParser&lt;int&gt;(int.TryParse); d[typeof(long)] = new GenericParser&lt;long&gt;(long.TryParse); d[typeof(float)] = new GenericParser&lt;float&gt;(float.TryParse); return d; } public static bool TryParse&lt;T&gt;(string s, out T result) { return ((GenericParser&lt;T&gt;)parsers[typeof(T)])(s, out result); } } public class Test&lt;T&gt; { public static T method1(string s) { T value; bool success = Support.TryParse(s, out value); return value; } } public static void Main() { Console.WriteLine(Test&lt;int&gt;.method1("23")); Console.WriteLine(Test&lt;float&gt;.method1("23.4")); Console.WriteLine(Test&lt;long&gt;.method1("99999999999999")); Console.ReadLine(); } } </code></pre> <p>I made a static dictionary holding a delegate for the TryParse method of every type I might want to use. I then wrote a generic method to look up the dictionary and pass on the call to the appropriate delegate. Since every delegate has a different type, I just store them as object references and cast them back to the appropriate generic type when I retrieve them. Note that for the sake of a simple example I have omitted error checking, such as to check whether we have an entry in the dictionary for the given type.</p>
