概述：
在目前很多機器都使用8G內存情況下，很多軟件卻無法有效使用更高內存，本文主要簡述使用C#語言開發的應用程序，使用系統自帶的Editbin工具開啓3G大內存使用。
詳細步驟(以VS2015舉例)：
第一步：找到editbin.exe文件
格式：VS版本\VC\bin\editbin.exe
以我機器爲例其位於VS軟件安裝目錄下：C:\Program Files (x86)\MicrosoftVisual Studio 14.0\VC\bin\editbin.exe
第二步：執行開啓大地址命令
命令格式：/largeaddressaware exe文件路徑
以我機器下一個WindowsFormsApplication1程序(.Net4.0)爲例：
/largeaddressaware C:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
命令行中運行如下：
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>editbin /largeaddressawareC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
第三步：運行後如下所示：
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：驗證是否確實開啓了大地址
在editbin.exe文件上方可以看到dumbin.exe文件。
命令格式：/headersexe文件路徑
以我機器下剛纔設置的WindowsFormsApplication1程序(.Net4.0)爲例：
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>dumpbin /headersC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
第五步：顯示如下信息即可確認獲取信息成功
C:\ProgramFiles (x86)\Microsoft Visual Studio 14.0\VC\bin>dumpbin /headersC:\Users\chuiwenwei\Desktop\WindowsFormsApplication1\WindowsFormsApplication1\bin\Debug\WindowsFormsApplication1.exe
