What is a method group in C#?

Question

I have often encountered an error such as \"cannot convert from \'method group\' to \'string\'\" in cases like:

var list = new List();
// ...          


        

Answer 1

Also, if you are using LINQ, you can apparently do something like myList.Select(methodGroup).

So, for example, I have:

private string DoSomethingToMyString(string input)
{
    // blah
}

Instead of explicitly stating the variable to be used like this:

public List GetStringStuff()
{
    return something.getStringsFromSomewhere.Select(str => DoSomethingToMyString(str));
}

I can just omit the name of the var:

public List GetStringStuff()
{
    return something.getStringsFromSomewhere.Select(DoSomethingToMyString);
}
