In C # development, multi-layer system architecture can simplify system development. Currently, three-tier petshop System Architecture Design and four-tier duwamish architecture are available. The following are some useful references: Duwamish

1. String fun1 () {String num = "ly ";Return num;}// InProgramWhen this method is used, no error is reported, because although num is released after the method is executed, the value of num is saved to a temporary storage unit, then copy the

Really benevolent, wise: too many methods, such as WCF, remoting, socket, and COM +. Remoting is suitable for LAN development. Socket (self-developed, requires a higher level), WebServices (Standard Protocol) is suitable for Wan development. COM +

When writing a winForm program, it is inevitable to use the DataGrid. Naturally, you need to set the column format, title, and so on! However, the column title is often set and does not respond, Which is disgusting! I have made a program over the

I am working on a small tool recently. the two-dimensional array and staggered array data calculated in. NET are imported into the Excel file and searched in the blog garden. Many predecessors have already pasted well-developed code. I made some

I just got started with json and found it interesting. I just used c # as an example to play with it. Here I will record it. Json data format: {"Id": 20547, "Name": "central south university", "NameEn": "central-south university", "AreaId": 190 },{ "

In development, we often encounter thread examples. If a background operation is time-consuming, we can start a thread to execute that time-consuming operation, and the program continues to execute. In some cases, synchronization and collaboration

First, the two classes have different working principles: the string class is a traditional string modification method. When you add a string to another string, the system first writes the two strings to the memory, delete the original string object,
