Replacing a word in a txt using c# in visual studios

Question

Does anyone no a way to replace a word in a txt file with another preset one? maybe using openfile or savefile to find the txt first and then use a text box to determin said word and replace it.

Example using open file to find the txt then typing a word e.g. dog to replace by using a the text box, and all words that have dog in the txt file get changed to cat. Im using visual studios 2012.

if its possible help is much appreciated

Well, you could do this with notepad and use its "find and replace" functionality. — Carra, Mar 02 '17 at 08:58

You could just use

string find = "word";
string replace = "replaced";
File.WriteAllText("C:\\yourfile.txt", File.ReadAllText("C:\\yourfile.txt").Replace(find, replace));
