.net 让编译成AnyCPU的程序在64位操作系统下以32位运行的方法

如果是iis，可以动态调整一个应用程序池选项就可以。但如果是winform就比较麻烦了，那就是使用CorFlags.exe，动态更改程序集的运行头，更改启动程序集就可以了。可能得借助bat，可实现让用户使用时无感。

使用方法如下（摘录微软官方的文档）：

The CorFlags Conversion tool allows you to configure the CorFlags section of the header of a portable executable image.

This tool is new in the .NET Framework version 2.0.

CorFlags.exe assembly [options]

 

Parameters

Argument	Description
assembly	The name of the assembly for which to configure the CorFlags.

 

Option	Description
/32BIT+	Sets the 32BIT flag.
/32BIT-	Clears the 32BIT flag.
/?	Displays command syntax and options for the tool.
/Force	Forces an update even if the assembly is strong-named.  Important If you update a strong-named assembly, you must sign it again before executing its code.
/help	Displays command syntax and options for the tool.
/ILONLY+	Sets the ILONLY flag.
/ILONLY-	Clears the ILONLY flag.
/nologo	Suppresses the Microsoft startup banner display.
/RevertCLRHeader	Reverts the CLR header version to 2.0.
/UpgradeCLRHeader	Upgrades the CLR header version to 2.5.  Note Assemblies must have a CLR header version of 2.5 or greater to run natively.

Remarks

If no options are specified, the CorFlags Conversion tool displays the flags for the specified assembly.
