Params is a keyword in C # development language, Params is mainly used when passing parameters to the function, that is, when the parameters of the function are not fixed. After the params keyword in the method declaration, no other parameters are

Both readonly and const are used to identify constants. Different initialization valuesThe constant modified by const must be assigned a value at the same time as the declaration.The readonly field can be assigned a value during initialization

When we use C # To develop programs, we often encounter unstable sessions and data loss. The following is a solution for Session data loss.1. In the WEB. modify the SESSION state saving mode in the CONFIG file, for example, 2. Start the System

Through the sina Weibo api Group microblog, I used the sdk provided by sina and made minor changes to it, skipping the oauth page authentication. This sdk is easy to use. The following describes the implementation method and provides a reference for

C #2005 and later do not support multi-thread direct access to interface controls (the interface creation thread is not the same as the access thread), but can be solved using delegate: 1. Declare a delegate and define an implementation function of

Overview The delegate in C # is similar to the function pointer in C or C ++. Delegate allows programmers to encapsulate method references in the delegate object. The delegate object can then be passed to the code that can call the referenced method,
