C# Closures, why is the loopvariable captured by reference?

Question

In this example, I\'m attempting to pass by value, but the reference is passed instead.

for (int i = 0; i < 10; i++)
{
    Thread t = new Thread(() =>         


        

Answer 1

You definitely want to read Eric Lippert's "Closing over the loop variable considered harmful":

• Part 1
• Part 2

In Short: The behavior you see is exactly how C# works.
