Use the csc command to compile the. cs file into. dll

In many cases, we need to compile the. cs file into a. dll file separately,
The procedure is as follows:
Open the command window-> Enter cmd to the console-> cd C: WINDOWSMicrosoft. switch NETFrameworkv1.1.4322 to the directory where vs.net is installed-> execute the csc command csc/target: library File. cs-> Generate a corresponding name under this directory. dll file (premise: Put. put the cs file in C: WINDOWSMicrosoft. NETFrameworkv1.1.4322 directory)
Csc commands are used in many ways. refer to the following,

------------------------------------
Translate File. cs to generate File.exe:
Csc File. cs
Compile File. cs to generate File. dll:
Csc/target: library File. cs
Compile File. cs and create My.exe:
Csc/out: My.exe File. cs
Compile all C # files in the current directory by optimizing and defining the DEBUG symbol. Output is File2.exe:
Csc/define: DEBUG/optimize/out: File2.exe *. cs
Compile all the C # files in the current directory to generate the debug version of File2.dll. No logo or warning is displayed:
Csc/target: library/out: File2.dll/warn: 0/nologo/debug *. cs
Compile all the C # files in the current directory as Something. xyz (a DLL ):
Csc/target: library/out: Something. xyz *. cs

Compile File. cs to generate File. dll: csc/target: library File. cs is the most widely used command. In fact, it can be simply written as csc/t: library File. another way of writing cs is
Csc/out: mycodebehind. dll/t: library mycodebehind. cs. You can specify the output file name by yourself.
Csc/out: mycodebehind. dll/t: library mycodebehind. cs mycodebehind2.cs. It is useful to install two cs files into A. dll file.
