C # unable to respond after a long running time

C # ProgramUnable to respond after a long running time

 

5 Supplement:Hello everyone, I have written a C # application. It takes about five minutes to run because of the long running time. However, when the window is running, there is a status that cannot respond, that is, the entire window can be clicked except the close and minimize buttons, but all others cannot be clicked, but the program can still run normally and there is no error. Please help me tell me why. Many programs do not respond when the CPU usage is 100%.

A large loop may occupy the main thread. multithreading is recommended. As long as the operation process does not involve interface operations, you can use a simple thread.
