This tutorial will provide a step-by-step guide on how to create a console application in C# that will count all ‘#’ characters in a text file. The application will read the text file line by line and count the number of ‘#’ characters in each line. The total number of ‘#’ characters in the text file will be displayed in the console window. This tutorial will also provide an example of how to use the StreamReader class to read the text file.<\/p>\n
