But for a beginner, let us go with creating a simple application using Linq and playing with database. Before writing the program, we need to know the following basic things. 1.

Now we start with creating simple program. The aim of the program is to display the Northwind customers data whose names are starting with "a" in a datagrid. Step 1: Create new C# wi...
When we are doing the coding, we need to use our own functions/methods to do a certain task. But while writing the function we may missed out the function details like why the function has been written . So whenever writing a function, if we use the documentation comments standard, it will help in the future whoever uses the function. Here is syntax; /// /// documentation block /// Here is the simple function defined in C# IDE; documentation comments added here; Intellisense is displaying the documentation comments.
