Does C# automatically initialize variables [closed]

Question

Can someone tell me if C# automatically initializes variables? If so, what are the default values?

No, and you can easily demonstrate this in a few lines of code. — woz

When you declare something inline it will not

int Foo()
{
    int bar; //Bar is not initlized, this code will not compile
    bar =  bar + 1;
    return bar;
}

However if you declare inside a class it will have a default value equal to default(type)

class Baz
{
   int bar;

   int Foo()
   {
        bar =  bar + 1;
        return bar; //default(int) is 0 so this returns "1"
   }
}

c# has no default value for variables if the variable scope is a method ... if the scope is at least field, the default value will be default(YourType) ... see http://msdn.microsoft.com/en-gb/library/xwth0h0d%28v=vs.80%29.aspx
