C # simple cross-thread assignment

Generally, C # is not allowed to assign values across threads. For example, there is a textbox in form1. If a new thread is opened

An exception occurs when the textbox value is assigned.

The specific practices are put forward in msdn, which is complicated and will not be mentioned.

Here is a simple method.

Most controls that can be assigned values have the invoke method. Isn't a delegate parameter required in the invode method,

That's simple. You can find a. Net custom delegate, such as threadstart. Therefore, you can do this:

Yourcontrol. Invoke (New threadstart (delegate (){
Yourcontrol. Text =Str; =Note: This STR is the variable in the form1 main thread.
}));

Simply put, you don't need to define the delegate, or write additional methods or other complicated things.
