Hi all, I've a problem with a file! but i think this is due to a code error i can't see. My program create a file with some information within. Then I search the information into the file, I fine them, and write them to screen (I use visual studio pro evaluetion ^^) with some textbox.. then I give the possibility to modify or delete the content found, to do this i make a string of all file (i will quote my code!) then i search use the replace string.replace("before";"after");, but this is not the problem. Now I've my string with all file modified, and ready to replace the all the old file! So i decide do rewrite all the file with the new string, but it doesn't change. If i decide to save it to a new file, than it works... but I don't need this! Code: /* Already created string named elimina (i'm italian..) with the content i want to delete in the file, and the string fileContent, with all the file content.*/ try { //Pass the file path and file name to the StreamReader constructor (some comments are of the msdn, not mine :D) StreamReader sr = new StreamReader("lista.txt"); // file name is lista.txt into the folder of the executable fileContent = sr.ReadToEnd(); // taken all the file fileContent = fileContent.Replace(elimina, ""); // deleted from the new string what I don't want anymore //close the file sr.Close(); Console.ReadLine(); } catch (Exception f) { Console.WriteLine("Exception: " + f.Message); } finally { Console.WriteLine("Executing finally block."); } /* Now I try to overwrite all the file lista.txt with the new string fileContent */ try { //Open the File StreamWriter sc = new StreamWriter("Lista.txt", false); sc.Write(fileContent); //close the file sc.Close(); } catch (Exception de) { Console.WriteLine("Exception: " + de.Message); } finally { Console.WriteLine("Executing finally block."); } This code give no error, but it doesn't work. If in the second stream of file I choose to write into a file named "what i want.txt" it works perfectly, creating the new file and writing on it the new content i wanted. Thanks for reading, and sorry for my italian-school english! (No good teacher... XD)
I'm going mad on this (in italian we say these exactly words, dunno if in english it means anything... sorry). But the conclusion is that visual studio is mad: This code totally work, IF you click 5 times on the button that should start that code... if you click it once, it doesn't works... do you know something similar o why it does so? Thanks
