We already know about delegates in C# and I have previously posted about basics of delegates in C#. Following are posts about basic of delegates I have written. Delegates in C# Multicast Delegates in C# In this post we are going to learn about Func Delegates in C#. As per MSDN following is a definition. “Encapsulates a method that has one parameter and returns a value of the type specified by the TResult parameter.” Func can handle multiple arguments. The Func delegates is parameterized type. It takes any valid C# type as parameter and you have can multiple parameters and also you have specify the return type as last parameters. Followings are some examples of parameters. Func<int T,out TResult> Func<int T,int T, out Tresult> Now let’s take a string concatenation example for that. I am going to create two func delegate which will going to concate two strings and three string. Following is a code for that.
