i have tryed this. but i says use of unassigned local variable 'co1 - co6' how can i fix that private void button8_Click(object sender EventArgs e) { string kundesti = @C:\Kunder\; try { string co1; string co2; string co3; string co4; string co5; string co6; foreach (string dir in Directory.GetFiles(kundesti *.txt)) { String[] allLines = File.ReadAllLines(dir); if (allLines.Length > 0) { string txtCipherText; txtCipherText = allLines[0]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co1 = decryptedText; } if (allLines.Length > 1) { string txtCipherText; txtCipherText = allLines[1]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co2 = decryptedText; } if (allLines.Length > 2) { string txtCipherText; txtCipherText = allLines[2]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co3 = decryptedText; } if (allLines.Length > 3) { string txtCipherText; txtCipherText = allLines[3]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co4 = decryptedText; } if (allLines.Length > 4) { string txtCipherText; txtCipherText = allLines[4]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co5 = decryptedText; } if (allLines.Length > 5) { string txtCipherText; txtCipherText = allLines[5]; string cipherText = txtCipherText.Trim(); string decryptedText = cryptoengine.Decrypt(cipherText true); co6 = decryptedText; } string[] row = { co1 co2 co3 co4 co5 co6}; ListViewItem lvi = new ListViewItem(row); listView3.Items.Add(lvi); } } catch { } }

Suppose all 200 or so of the text file names are stored in a string array called filePaths. Then you could populate the ListView as follows (Windows Forms assumed): using System.IO; //... listView1.BeginUpdate(); foreach(string filePath in filePaths) { string[] rows = File.ReadAllLines(filePath); ListViewItem lvi = new ListViewItem(rows); listView1.Items.Add(lvi); } listView1.EndUpdate(); EDIT As you've closed the thread I can only answer your second post by editing this post. Anyway the answer is to initialize your variables to empty strings: string co1 = ; string co2 = ; string co3 = ; string co4 = ; string co5 = ;
