要不给我把代码EMAIL给你.email?
代码如下：
private void button1_Click_1(object sender, System.EventArgs e)
{
FolderBrowser folder=new FolderBrowser();
folder.Title="Please select one folder what you need.";
if(folder.ShowDialog()==DialogResult.OK)
{
string sPath=folder.DirectoryPath;
if(sPath=="")
{
return;
} MessageBox.Show(sPath);
//lvFiles.Items.Clear();
//AddDirectoryItem(sPath);
//AddFileItem(sPath);
}
}其它都没改。email:[email protected]
