《CLR Via C#》 C# Compiler

1、CSC.exe的存放位置

如果想要使用C# Compiler，只要在命令提示符（command prompt）中输入csc.exe就可以了。csc.exe的路径在C:\Windows\Microsoft.NET\Framework64\v4.0.30319下。（注意，我的电脑的操作系统是64位。）
You can invoke the C# compiler by typing the name of its executable file (csc.exe) at a command prompt. The csc.exe executable file usually is located in the Microsoft.NET\Framework\Version folder under the Windows directory.




如果使用Visul Studio Command Prompt的命令提示符，一些“环境变量”会帮你设置好，就不需要自己再进行设置了。
If you use the Visual Studio Command Prompt window, all the necessary environment variables are set for you.

如果你使用标准的cmd.exe文件，就需要自己设置一下，可以参考“How to: Set Environment Variables for the Visual Studio Command Line”地址：https://msdn.microsoft.com/zh-cn/library/1700bbwd.aspx

2、C# Compiler的一些示例

Compiles File.cs producing File.exe:

csc File.cs

Compiles File.cs producing File.dll:

csc /target:library File.cs

Compiles File.cs and creates My.exe:

csc /out:My.exe File.cs

Compiles all the C# files in the current directory, with optimizations on and defines the DEBUG symbol.The output is File2.exe:

csc /define:DEBUG /optimize /out:File2.exe *.cs

Compiles all the C# files in the current directory producing a debug version of File2.dll.No logo and no warnings are displayed:

csc /target:library /out:File2.dll /warn:0 /nologo /debug *.cs

Compiles all the C# files in the current directory to Something.xyz (a DLL):

csc /target:library /out:Something.xyz *.cs

C# Compiler Options Listed by Category

Option	Purpose
@	Reads a response file for more options.
/?	Displays a usage message to stdout.
/additionalfile	Names additional files that don't directly affect code generation but may be used by analyzers for producing errors or warnings.
