Q:

ways to call Func delegate inside Func delegate

I am new Func delegate in my existing code there is one function . can someone explain How to work with Func delegate?
public static ListColumn SetBColorFunction(this ListColumn column, Func<object, Func<object>, Color> colorFunction)
{
    column.BackColorFunction = colorFunction;
    return column;
}

Now i want to know what are the ways to call this above function?

A:

Your method description:

SetBColorFunction is an extension method so you need not pass the first parameter.
It takes a method which takes a delegate and a Color as parameters and returns an object. The delegate can take a method which returns an object and doesn't take any argument.

So with this understanding try the following solutions.
Solution 1:
Color Callback(object o, Func<object> func)
{
    object obj = func();
    return new Color();
}

void Consumer()
{
    ListColumn listColumn = new ListColumn();
    listColumn.SetBColorFunction(Callback)
}

Solution 2:
Using lambda.
void Consumer()
{
    ListColumn listColumn = new ListColumn();
    listColumn.SetBColorFunction((obj, func) => {// Do your work and return object})
}
