Difference between Parse and TryParse

 If a number in a string format you have two options to convert into int or string 

1. Parse--Parse() method throws an exception if it can not parse the value 

2. TryParse()- TryParse() method returen a boolean whether it is succeeded or failed.

Use Parse() if you are sure value is valid, otherwise use TryParse.. 

For example- We are using TryParse beacuse our number is invalid.

string num= "100lk";

int result= 0;

bool isConversionsuccessful= int.TryParse(num,out result)

if(isConversionsuccessful)

{

Console.Writeline(result);

}

else

{

Console.Writeline("Please enter valid number");

}
