Thank you for your explanation.

I was thinking before that Amit wanted to convert any character string to an int which isn't possible.

However, if the string represents an int (such as "123" or "4567"), then you can of course parse it to an int.

The methods which could be used would be:

int i = Int32.Parse("123");
Console.WriteLine(i); // 123

int j;
bool isValid = Int32.TryParse("4567", out j);
if (isValid) Console.WriteLine(j); // 4567

int k = Convert.ToInt32("890");
Console.WriteLine(k); // 890

Convert.ToInt32 also has overloads which enables you to convert hex, octal or binary strings to ints.

Whatever we input from the console screen is realized as a string and converts it to a form of our choice.

Please explain the string to int convertion in detail.

You can't convert a string into an int.

However, you can convert a single char into an int:

char c = 'A';
int i = (int)c;
Console.WriteLine(i); // 65
