How to Safely Convert Strings to Integers in C#?

The conversion of string to integer in the integer

In data processing, it is often necessary to transform between different data types. A common scenario is to convert the number of numbers into an integer (INT32) to store it into the database.

C# mainly have two main methods that can achieve this conversion:

<.> 1. int32.parse method

This method directly converts the specified string to an integer. If the string is not an integer representation form, the Formatexception exception will be thrown.

<code class="language-csharp">int x = Int32.Parse(TextBoxD1.Text);</code>

<.> 2. int32.tryparse method

This method attempts to convert the string to an integer and return a Boolean value to indicate whether the conversion is successful. It is recommended to use this method because it avoids an abnormal treatment when the input string is invalid.

The comparison of the comparison of paars and trypars

<code class="language-csharp">int x = 0;
bool success = Int32.TryParse(TextBoxD1.Text, out x);</code>

The difference between

Parse and TryParse is abnormal treatment. The PARSE method will throw abnormality when the conversion fails, and the TryParse method returns false and allows you to deal with the situation where the conversion fails accordingly.

Example of using the TryParse method

In this example, the TRYPARSE method uses the value of the conversion with the output parameter x. If the conversion is successful, the IF statement block will be executed; otherwise, if the conversion fails, you can take appropriate operation.
