Characters Validation in Name field using C-sharp Language

Parsing the most commonly used technique in c-Sharp and Higher Level Languages

Parsing term actually refers to the coversion from one data type to another. In programming parsing technique is very important while concering with user data of different data types. You need to convert a string containing char digits into an integer, allowing you to use a numeric value. There are several methods, such as int.Parse, that are ideal for this. Here we look at three useful methods that are effective, assuming your code must only accept very simple input strings, using code in the C# programming language.

String input data:
"999" // input is integer
"-26" //input is signed integer
"abc" //string is the input value
"0.123" //input is of float type
