Example
class Example {
public static int method(int num)
{
return num + num;
}
static public void Main()
{
Func<int, int> myfun = method;
Console.WriteLine(myfun(10));
}
}
Output:
20
Func Delegate With Anonymous Methord
An anonymous method can also be used with a Func delegate. As seen in the case below.
Example:
Func<int, int, int> val = delegate(int x, int y, int z)
{
return x + y + z;
};
Func Delegate With Lambda Expressions
With lambda expressions, you may also utilize a Func delegate. As seen in the case below.
Example:
Func<int, int, int, int> val = (int x, int y, int z) = > x + y + z;
