Closures in c# .NET

Check these two cases

private void button4_Click(object sender, EventArgs e)
{
Func<string, string> GreetHellow = delegate(string var1)
{ return " Hellow 2 " + var1; };
Func<string, string> GreetHi = var1 => " hi 2 " + var1;
Console.WriteLine(GreetHellow("Janaganamana"));
Console.WriteLine(GreetHi("Janaganamana"));
}



OR


Func<string, string> GreetHellow = delegate(string var1)
{ return " Hellow 2 " + var1; };
Func<string, string> GreetHi = var1 => " hi 2 " + var1;
private void button4_Click(object sender, EventArgs e)
{

Console.WriteLine(GreetHellow("Janaganamana"));
Console.WriteLine(GreetHi("Janaganamana"));
}

Both give following output
//Hellow 2 Janaganamana
//hi 2 Janaganamana

Now check a similar case
private void button3_Click(object sender, EventArgs e)
{
var inc = GetAFunc();
Console.WriteLine(inc(5));
globalint = 10;
Console.WriteLine(inc(5));
}

static int globalint = 0;

public static Func<int, int> GetAFunc()
{
int x = 10; int y = 10;
var myVar = x + y + globalint;

Func<int, int> inc = delegate(int var1)
{
myVar = myVar + 1;
return var1 + myVar;
};
return inc;
}

Notice the following lines are visited only once ( once to get func pointer)

output is
26
27

so "globalint = 10;" is not reflected.
Also notice "myVar " is a live variable that keeps latest value (myVar = myVar +1 " keeps incrementing.

It may look little ODD (but is Fair - CLOSURE) while breakpoint dont stop @ "var myVar = x + y + globalint;
"
It stops only once while fetching func pointer.

Notice myVar works within the scope (CLOSURE)of this button click event (it incremented within this scope.)
