I tried to compile a class containing only the following method but it gives the error
"Error 1 A local variable named 'i' cannot be declared in this scope because it would give a different meaning to 'i', which is already used in a 'child' scope to denote something else".
Why is it so
Please help..
public static void M()
{
{
char i = 'a';}
int i = 0;}
Why is this code giving a compile error?

if ( something )
{
int i = 10; //A
Console.WriteLine( i );
}
int i = 10; //B
The compiler error given for the line marked B says:
Well, duh! No it won't! A variable is in scope from its point of declaration, so the 'i' introduced at B will NOT give a different meaning to the one introduced at A.
Grrrr!

i"is declared in the outer block and cannot be redeclared in the inner block. In this case C# behave like if "i" is a method: The method scope is the block in with you declarate it, do you can call to a method "b" from the method "a" declarated before.You can found the theory in http://msdn.microsoft.com/library/default.asp url=/library/en-us/csspec/html/vclrfcsharpspec_3_3.asp

you declared a variable twice. If you made the first in a if or for statement it should work.
