How to Convert a String to an Int Using Int32.TryParse()Ĭompared to the int.Parse() method, int.TryParse() is a safer way to convert a string to a 32-bit signed integer. The Convert.ToInt32() method has two exceptions, FormatExceptionand OverflowExceptionand is able to convert a null variable to 0 without throwing an exception. We then use the Convert.ToInt32() method to convert this string to an integer and assign it to a variable named num. In the code block above, we have declared a string variable, numString, and assigned it a value. Here is an example: string numString = "123" This method takes a string variable as input and returns an integer. How to Convert a String to an Int Using Convert.ToInt32()Ĭonvert.ToInt32() is a static method provided by C# to convert a string to a 32-bit signed integer. Here is how to do this: string numString = "12" Īnother possible solution is using TryParse(), which we'll discuss below. To avoid this issue, you can use a try-catch block while using int.Parse(). The downside of using the int.Parse() method is that an exception will be thrown if it cannot be successfully parsed to an integer. The method takes a string variable called numberStringand converts it to an int. The above code shows how to convert a string to an Integer using the int.Parse() method. Here is an example: string numberString = “8” Int32.Parse() is the easiest way to convert a string to an integer. How to Convert a String to an Int Using Int32.Parse() You can convert a string to an Int using the following method. Int32is a built-in value type that represents a 32-bit signed integer. The Intkeyword is an alias for the System.Int32 type, and it is utilized for declaring variables that can hold 32-bit signed integers within the range of -2,147,483,648 to 2,147,483,647. Whether you are a beginner or an experienced programmer, this guide will provide a user-friendly introduction to the topic. ![]() This article will also provide examples to help you understand the syntax of each method. ![]() This article will explore some of the most common methods to convert a string to an integer in C# using the int.Parse(), int.TryParse(), and Convert.ToInt32() methods. Whether you are working with user input or data from an external source, converting a string to a number is a common task for developers. There are various situations where you need to convert a string to a number.
