Scope of variables inside anonymous functions in C#
- by Vinod
I have a doubt in scope of varibles inside anonymous functions in C#.
Consider the program below:
delegate void OtherDel(int x);
public static void Main()
{
OtherDel del2;
{
int y = 4;
del2 = delegate
{
Console.WriteLine("{0}", y);//Is y out of scope
};
}
del2();
}
My VS2008 IDE gives the following errors:
[Practice is a class inside namespace Practice]
1.error CS1643: Not all code paths return a value in anonymous method of type 'Practice.Practice.OtherDel'
2.error CS1593: Delegate 'OtherDel' does not take '0' arguments.
It is told in a book: Illustrated C# 2008(Page 373) that the int variable y is inside the scope of del2 definition.
Then why these errors.
