string dirpath = Directory.GetCurrentDirectory();
Prependthis dirpath to the filename to get the complete path.
前面加上这个dirpath到文件名，以获得完整路径。
As @Dan Puzey indicated in the comments, it would be better to use Path.Combine
正如@Dan Puzey 在评论中指出的那样，最好使用Path.Combine
Path.Combine(Directory.GetCurrentDirectory(), filename)

Use Path.GetFullPath():
使用 Path.GetFullPath()：
http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx
http://msdn.microsoft.com/en-us/library/system.io.path.getfullpath.aspx
This should return the full path information.

try:
尝试：
string fileName = @"test.txt";
string currentDirectory = Directory.GetCurrentDirectory();
string[] fullFilePath = Directory.GetFiles(currentDirectory, filename, SearchOption.AllDirectories);
it will return full path of all such files in the current directory and its sub directories to string array fullFilePath. If only one file exist it will be in "fullFileName[0]".
它会将当前目录及其子目录中所有此类文件的完整路径返回到字符串数组 fullFilePath。如果只有一个文件存在，它将在“fullFileName[0]”中。
