| How to convert string to int in C#? |
In C#, it is often necessary to convert a string to an integer. This can be useful when working with user input, or when you need to perform calculations with numeric values. In this blog, we will discuss the different ways to convert a string to an integer in C#.
Method 1: Convert.ToInt32()
The most common way to convert a string to an integer in C# is to use the Convert.ToInt32() method. This method takes a string as its parameter and returns an integer.
Syntax:
string str = "10";
int num = Convert.ToInt32(str);
In this example, we use the Convert.ToInt32() method to convert the string "10" to an integer. The resulting integer is stored in the variable num.
Method 2: int.Parse()
Another way to convert a string to an integer in C# is to use the int.Parse() method. This method takes a string as its parameter and returns an integer.
Syntax:
string str = "10";
int num = int.Parse(str);
In this example, we use the int.Parse() method to convert the string "10" to an integer. The resulting integer is stored in the variable num.
Method 3: int.TryParse()
The int.TryParse() method is another way to convert a string to an integer in C#. This method takes a string as its first parameter, and an integer as its second parameter. It returns a boolean value that indicates whether the conversion was successful or not. If the conversion was successful, the resulting integer is stored in the second parameter.
Syntax:
string str = "10";
int num;
bool success = int.TryParse(str, out num);
In this example, we use the int.TryParse() method to convert the string "10" to an integer. The resulting integer is stored in the variable num, and the method returns a boolean value that indicates whether the conversion was successful or not.
In this blog, we have discussed the different ways to convert a string to an integer in C#. We have covered the Convert.ToInt32() method, the int.Parse() method, and the int.TryParse() method. Each of these methods has its own advantages and disadvantages, and the best method to use will depend on the specific requirements of your code. It is important to understand the differences between these methods and to choose the one that is most appropriate for your situation. With these methods, you can easily convert strings to integers in C# and perform calculations with numeric values.
