  When we use C # To Call DLL files written by Delphi or Vc, if they are not COM + type DLL files, we need to use the form of hosting to call them. For example: [Dllimport ("sccard. dll", callingconvention = callingconvention. stdcall)]Public

Ref is the address for passing parameters, and out is the return value. There are some similarities between the two, but there are also differences. You must assign values to variables before using ref. The out function will clear the variable,

During the project today, the recharge card password is generated randomly due to the need to generate recharge cards in batches. ProgramDuring the operation, the password of the recharge card is almost the same, so the manual debugging and

The previous blog post: Starting from C #5.0: summarizes the development history of C # asynchronous call methods and the development history of Asynchronous Method calls. For more information about C #2.0 to 5.0, I wrote the following in the

In many cases, we need to obtain the output content of the command line through programming. After studying it for a lot of time, we finally got it done. There are two methods to obtain the output content of the command line: traditional and

First, we define the cell class of the object to be operated. In this class, there are two methods: readfromcell () and writetocell. The consumer thread will call readfromcell () to read and display the cellcontents content. The producer process

Expression indicates the object you want to trace. It is usually an object reference. Generally, if you want to protect an instance of a class, you can use this; if you want to protect a static variable (such as mutual exclusion) Code In a static

Many of my friends will encounter the problem that the label content to be displayed is too long but cannot be wrapped in a line feed during winform development. Here I have summarized several methods for your reference:First, set the label autosize

Note that other threads are attached to the thread where the main () function is located. The main () function is C # Program The start thread can be called the main thread. If all foreground threads are stopped, the main thread can be terminated,
