In C#, char and int are two different data types. A char represents a single character, while an int represents a whole number. However, there are situations where you might need to convert a char to an int, such as when you need to perform mathematical operations on a character code. In this article, we will discuss how to convert a char to an int in C#.The ASCII Code TableBefore we dive into the conversion process, let’s take a brief look at the ASCII code table. The ASCII code table is a set of codes that represent characters in the English language. Each character is assigned a unique code, ranging from 0 to 127.For example, the code for the letter ‘A’ is 65, and the code for the letter ‘B’ is 66. You can find the ASCII code table online, and it is a handy reference when you need to work with characters and their corresponding codes.Converting a Char to an IntNow that we understand the ASCII code table, let’s move on to the conversion process. In C#, you can convert a char to an int using the Convert.ToInt32() method or by casting the char to an int.Here’s an example of using the Convert.ToInt32() method:char myChar = 'A';int myInt = Convert.ToInt32(myChar);In this example, we declare a char variable named myChar and assign it the value ‘A’. We then declare an int variable named myInt and use the Convert.ToInt32() method to convert the char to an int. The result is that myInt now holds the value 65, which is the ASCII code for the letter ‘A’.Alternatively, you can also use casting to convert a char to an int. Here’s an example:char myChar = 'A';int myInt = (int)myChar;In this example, we cast the char variable myChar to an int using the (int) notation. The result is that myInt holds the value 65, which is the ASCII code for the letter ‘A’.ConclusionIn conclusion, converting a char to an int in C# is a simple process that can be done using either the Convert.ToInt32() method or by casting the char to an int. By understanding the ASCII code table and how characters are represented as codes, you can perform mathematical operations on characters and manipulate them in your C# programs.
