Exception of type 'System.OutOfMemoryException' was thrown.

[OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.] 在装有4G物理内存的32位OS机器上内存不足，原因是：The common language runtime throws an OutOfMemoryException error if it cannot allocate physical memory—or reserve sufficient virtual memory (VM)—to fulfill allocation request. By default, the addressable virtual memory space that is available for the process is 2 GB. If the virtual address space is exhausted, the operating system cannot allocate more physical memory for the process.

解决方法

解决方法是两步：1. 配置机器boot.ini 为/3g 内存选项 2. 配置VS2010支持3G内存模式 （如果你是64位Win7或者WindowsServer2003 64位，请自动忽略本文）

To enable this feature, add the /3GB switch to the Boot.ini file. This enables applications to use the first 3-GB of the address space on the following systems:

• Windows Vista
• Windows Server 2003
• Windows XP Professional
• Windows 2000 Datacenter Server
• Windows 2000 Advanced Server
• Windows NT Server 4.0 Enterprise Edition

配置boot.ini支持 / 3G

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOW S
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Micro soft Windows XP Professional" /fastdetect /NoExecute=OptIn
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="XP Professional 3GB switch" /3GB /USERVA=2900 /fastdetect /NoExecute=OptIn

配置VS2010支持3g内存

Using the Visual Studio command prompt, cd到\Microsoft Visual Studio 10.0\Common7\IDE\，然后执行command: editbin /LARGEADDRESSAWARE devenv.exe

重启机器即可。（参考资料：这个，这个，这个，和这个）
