推荐答案

string searchFile = "searchThisFile.txt";
string searchFilePath = "";

bool found;

System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();

foreach (System.IO.DriveInfo drive in drives)
{
    if (drive.DriveType == System.IO.DriveType.Removable)
    {
        if (drive.IsReady)
        {
            string[] files = System.IO.Directory.GetFiles(drive.Name);

            foreach(string file in files)
            {
                if (System.IO.Path.GetFileName(file) == searchFile)
                {
                    searchFilePath = file;
                    found = true;

                    break;
                }
            }
        }

        if(found)
        {
            break;
        }
    }
}

if(found)
{

// File found!
// The path is inside the string
// Process it

}

此处的代码获取所有可移动驱动器(USB记忆棒等)并搜索您要处理的文件(searchFile).如果找到它，它将停止搜索并将找到的路径存储在searchFilePath中.

Found将被设置为true，这是因为否则它仍将搜索您不需要的所有其他驱动器.

希望这对您有所帮助，
祝你好运

The code right here gets all removeable drives (USB sticks etc.) and searches for the file you want to process (searchFile). If it finds it it stops searching and store the found path inside searchFilePath.

Found will be set to true, this because otherwise it would still be searching all other drives which you don''t want.

Hope this helped,
Good luck
