Project architecture: All functions in the system are implemented separately in each dll. The main program loads the corresponding dll of each menu. For some highly repetitive functional code, you can write it in a main dll for other functions to

Recently, serial communication programming is involved in the project. When my teammates are working on this module, they encounter a problem that many people may encounter, that is, receiving data conflicts or loss. It took nearly two hours for my

Several common C # operations on Word tables? Let's take a look at the demo: Bool SaveChange=False;  // C # operate Word tables Object Missing=System. Reflection. Missing. Value;   Object Template=(Object) TemplateFilePath;  

The difference between the shallow copy and the deep copy is that the processing value type is the same as the processing reference type. When the value type is processed, both of the two copy modes directly allocate a new memory area and copy the

Indexof (): locates the character and string from the front to the back in the string. All return values are absolute positions in the string. If it is null, it is-1. String test = "asdfjsdfjgkfasdsfsgfhgjgfjgdddd"; test. indexof (d) = 2 // locate

Recursive methods should be familiar to everyone. In short, they are called internally by the method itself, so that repeated and repeated executions are repeated, But worry about endless loops...   When the menu needs to be dynamically generated by

Usage,   ImageRas _ Ras = new ImageRas (@ "D: empest. ras ");PictureBox1.Image = _ Ras. Image;   _ Ras. SaveRas (@ "d: empOK. ras ");   I only implemented the 24-bit color and 8-bit color structure, which is too simple. Only the file header and data

The difference between passing a ref variable before a reference type and passing a reference type variable without a ref variable is not clear all the time. Recently, a friend on the Internet gave me a question, after careful consideration and
