概述：
在目前很多机器都使用8G内存情况下，很多软件却无法有效使用更高内存，本文主要简述使用C#语言开发的应用程序，使用系统自带的Editbin工具开启3G大内存使用。
详细步骤(以VS2015举例)：
第一步：找到editbin.exe文件
格式：VS版本\VC\bin\editbin.exe
以我机器为例其位于VS软件安装目录下：C:\Program Files (x86)\MicrosoftVisual Studio 14.0\VC\bin\editbin.exe
第二步：执行开启大地址命令
命令格式：/largeaddressaware exe文件路径
以我机器下一个WindowsFormsApplication1程序(.Net4.0)为例：
/largeaddressaware C:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
命令行中运行如下：
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>editbin /largeaddressawareC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
第三步：运行后如下所示：
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>editbin /largeaddressawareC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
Microsoft(R) COFF/PE Editor Version 14.00.23026.0

第四步：验证是否确实开启了大地址
在editbin.exe文件上方可以看到dumbin.exe文件。
命令格式：/headersexe文件路径
以我机器下刚才设置的WindowsFormsApplication1程序(.Net4.0)为例：
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>dumpbin /headersC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
第五步：显示如下信息即可确认获取信息成功
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>dumpbin /headersC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
Microsoft(R) COFF/PE Dumper Version 14.00.23026.0
