OpenFileDialog Error: 'Path is not of legal form'

Question

代码如下：

OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Select script to load...";
fDialog.Filter = "Text Files|*.txt";

fDialog.ShowDialog();

string text = File.ReadAllText(Path.GetFullPath(fDialog.FileName));
if (text.Length > 0)
{
    LuaCArea.Text = text;
} 

我收到错误：

The path is not of a legal form.

有什么想法吗？

等待 OpenFileDialog 结果无效，不要使用 Path.GetFullPath

OpenFileDialog fDialog = new OpenFileDialog();
fDialog.Title = "Select script to load...";
fDialog.Filter = "Text Files|*.txt";

if(fDialog.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    LuaCArea.Text = File.ReadAllText(fDialog.FileName);
}
