C# Remove Duplicate Lines From Text File

There are various methods to remove duplicate lines from text file. Some of these are easier to implement than others. The approach to be taken can depend on the size of the text file and the expected number of matching lines. Here we focus on small size text files.

String[] TextFileLines = File.ReadAllLines("textFile.txt");

TextFileLines = TextFileLines.Distinct().ToArray() ;

File.WriteAllLines("textfile.txt", );

In the C# code above, first we read all text file lines and stored these lines into an array. Then we used Distinct() function, a built in function of C#, to remove duplicates. Finally we wrote these distinct lines back to the file.

How to make Web Development fast??? (A trick to Quick Web Development)

Hi, Here I am going to give you a trick to quickly develop web pages. The trick is simple. This trick will be very useful and time saving when there is repetition of work. For example, making create, read, update, delete pages (CRUD operations) on a table in the database. If your application contains 25 or more tables in the database, and creating CRUD pages on a single table takes 2 hour, then it will take 50 hours to make CRUD pages for all the tables. You can reduce the time by making code generator for your web application.

Firstly create CRUD pages for a table. Then create an application whose inputs will be the table name and schema name. The application will automatically get the fields of the table and display it to you. You specify the appearence of the fields (like textbox, dropdownlist, checkbox etc). After submitting it will generate code for you by making replacements necessary in the code you created for one table.
