《CLR Via C#》使用CSC.exe进行单文件的编译

1、新建一个Program.cs文件，并写入代码

在目录E:\LiuSen\VS\test下，新建一个Program.cs文件，输入以下代码

using System;

namespace MyConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello world!");
            Console.ReadKey();
        }
    }
}

2、用CSC.exe对Program.cs进行编译

打开Developer Command Prompt for VS2013，并转到目录E:\LiuSen\VS\test下，并使用如下命令进行编译：

csc.exe /out:Program.exe /t:exe /r:MSCorLib.dll Program.cs

3、运行Program.exe文件

4、知识总结

4.1、/r:MSCorLib.dll可以省略掉

MSCorLib.dll is a special file in that it contains all the core types: Byte, Char, String, Int32, and many more. In fact, these types are so frequently used that the C# compiler automatically references the MSCorLib.dll assembly. In other words, the following command line (with the /r switch omitted) gives the same results as the line shown earlier.【MSCorLib.dll是一个经常被引用的类库，，因此/r MSCorLib.dll参数可以省略】

csc.exe /out:Program.exe /t:exe Program.cs

4.2、/out: Program.exe 和 /t:exe 也可以省略掉

Furthermore, because the /out:Program.exe and the /t:exe command-line switches also match what the C# compiler would choose as defaults, the following command line gives the same results too.

csc.exe Program.cs

4.3、如果不想让MSCorLib.exe参与编译，可以使用/nostdlib

If, for some reason, you really don't want the C# compiler to reference the MSCorLib.dll assembly, you can use the /nostdlib switch. Microsoft uses this switch when building the MSCorLib.dll assembly itself. For example, the following command line will generate an error when CSC.exe attempts to compile the Program.cs file because the System.Console type is defined in MSCorLib.dll.【如果不想让c# compiler引用MSCore.dll文件，可以加上 /nostdlib参数】

4.4、Windows支持的三种Application类型

Windows supports three types of applications. To build a console user interface (CUI) application, specify the /t:exe switch; to build a graphical user interface (GUI) application, specify the /t:winexe switch; and to build a Windows Store app, specify the /t:appcontainerexe switch.【在这里，主要注意/t参数的三种类型】
