How Can I Pass Parameters to a ThreadStart Delegate in C#?

Passing Parameters to ThreadStart Method in Thread

When creating a thread in C#, you often need to pass parameters to the thread's delegate, such as the ThreadStart delegate. This allows you to pass information from the main thread to the newly created thread.

To pass parameters to ThreadStart, you can use lambda expressions. Consider the following example:

public void download(string filename)
{
    // download code
}

Thread thread = new Thread(() => download(filename));

In this code, the lambda expression () => download(filename) captures the filename variable from the surrounding scope and passes it as a parameter to the download method when the thread starts.

Advantages of Using Lambda Expressions:

• Compile-time checking: Lambda expressions avoid the need to cast from an object when accessing the parameters passed to ThreadStart.
• Multiple parameters: You can easily pass multiple parameters using lambda expressions, providing flexibility in parameter handling.

By leveraging lambda expressions, you can effectively pass parameters to ThreadStart and retain compile-time checking, making your code more robust and easier to maintain.
