Question

我希望Filewatcher能够看到FileBrowseBox的路径，但是使用FileBrowseBox，你必须选择一个文件。我如何看文件所在的路径？所以我需要FileWatch输入FileBrowseBox。我不知道怎么做。我为你们准备了一个代码和一个版画屏幕。

我确实需要传输文件，但我也需要它所在的路径。如何在FileSystemWatcher1中的FilebrowseBox中放置文件的路径？

Answer 1

这是一个应该修复它的例子，示例中的字符串文件路径应该是你的一个文本框

string filePath = @"C:\MyDir\MySubDir\myfile.ext";
string directoryName;
int i = 0;

while (filePath != null)
{
directoryName = Path.GetDirectoryName(filePath);
Console.WriteLine("GetDirectoryName('{0}') returns '{1}'",
    filePath, directoryName);
filePath = directoryName;
if (i == 1)
{
    filePath = directoryName + @"\";  // this will preserve the previous path
}
i++;
}

获取文件的路径。 C＃
