我尝试过：



如果我把sFileName这个给出错误，这样sFileName

它传递当前文件夹名

OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.DAT)|*.DAT";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
string sFileName;

if (choofdlog.ShowDialog() == DialogResult.OK)
{
sFileName = choofdlog.FileName;

}
FileStream fs = new FileStream(sFileName, FileMode.Open, FileAccess.Read);

this give error if I put sFileName this,this way "sFileName"
it pass current folder name

Please help me

Thanks in advance

it pass current folder name

推荐答案

试试这个：

Try this:

OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.DAT)|*.DAT";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
    if (choofdlog.ShowDialog() == DialogResult.OK)
    {
    foreach (string sFileName = choofdlog.FileNames)
        {
        using (FileStream fs = new FileStream(sFileName, FileMode.Open, FileAccess.Read))
        {
            {
               ...
            }
        }
    }

当你使用multiselect时，你应该使用FileNames集合，而不是单个FileName - 你不应该试图打开文件如果用户在对话框中按取消。

When you use multiselect, you should work from the FileNames collection, not a single FileName - and you shouldn't be trying to open files if the user presses "Cancel" in the dialog.
