推荐答案

我尝试了上面的答案，可惜它不是简单的，因为它似乎...

I tried the answers above, unfortunately it was not simple as it seems...

第一个答案，使用管理对象看起来像这样只可惜不支持Windows XP中的格式方法的正确途径。

The first answer, using the management object looks like the correct way of doing so but unfortunately the "Format" method is not supported in windows xp.

第二和第三答案工作，但需要用户确认操作。

The second and the third answers are working but require the user to confirm the operation.

为了做到这一点，而无需用户进行任何干预我使用重定向过程的输入和输出流的第二个选项。当我只重定向输入流的过程中失败了。

In order to do that without any intervention from the user I used the second option with redirecting the input and output streams of the process. When I redirecting only the input stream the process failed.

下面是一个例子：

DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
    if (d.IsReady && (d.DriveType == DriveType.Removable))
    {
    	ProcessStartInfo startInfo = new ProcessStartInfo();
    	startInfo.FileName = "format";
    	startInfo.Arguments = "/fs:FAT /v:MyVolume /q " + d.Name.Remove(2);
    	startInfo.UseShellExecute = false;
    	startInfo.CreateNoWindow = true;
    	startInfo.RedirectStandardOutput = true;
    	startInfo.RedirectStandardInput = true;

    	Process p = Process.Start(startInfo);

    	StreamWriter processInputStream = p.StandardInput;
    	processInputStream.Write("\r\n");

    	p.WaitForExit();

    }
}
