`int.Parse() vs Convert.ToInt32(): Which C# Method Should I Choose for String-to-Integer Conversion?`

The character string in the integer to integer conversion: int.Parse() Comparison with Convert.ToInt32()

Data processing, especially in programming, often need to be converted between different data types. In C#, the two common methods of converting string to integer are int.Parse() and Convert.ToInt32().

The difference between int.Parse() Convert.ToInt32() The main difference between

and

is how they handle invalid input: int.Parse() Convert.ToInt32()

:
• This method expects that entering the string is an effective integer representation form. If the input is invalid, it will cause abnormal. int.Parse() FormatException :
This method accepts valid and invalid input string. If the input is not an effective integer, it returns 0 instead of cause abnormalities.
• Convert.ToInt32() Which method to choose?
The choice of method depends on the expected scene:

It is recommended to use

:

You expect that entering the string is always an effective integer. int.Parse() You need to cause abnormalities in the case of invalid input.

• It is recommended to use
:

You are collecting user input and hoping that there may be invalid numbers. Convert.ToInt32() You want to better control the error treatment.

Other precautions
Accepting objects as parameters, and can also process air value without causing abnormalities.
Because can process effective and ineffective inputs, it may be slightly slower than

.
