private void button1_Click(object sender, EventArgs e) {     int size = -1;     OpenFileDialog openFileDialog1 = new OpenFileDialog();     DialogResult result = openFileDialog1.ShowDialog(); // Show the dialog.     if (result == DialogResult.OK) // Test result.     {        string file = openFileDialog1.FileName;        try        {           string text = File.ReadAllText(file);           size = text.Length;        }        catch (IOException)        {        }     }     Console.WriteLine(size); // <-- Shows file size in debugging mode.     Console.WriteLine(result); // <-- For debugging use. }

var FD = new System.Windows.Forms.OpenFileDialog(); if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {     string fileToOpen = FD.FileName;      System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);      //OR      System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);     //etc }
