Parse and TryParse
Posted by Virendra Dugar on January 30, 2009
Parse method is used to parse any value to specified data type.
string test = “42”;
Result = Int32.Parse(test);
This will work fine but what if when you are not sure about the value of string variable test. As for example if test=”abc” and if you try to use above method, .NET will throw an exception as you are trying to convert string data to integer.
TryParse is a good method if the string you are converting to an interger is not always numeric.
TryParse method returns a boolean to denote whether the conversion has been successfull or not, and returns the converted value through an out parameter.
**declare variable iResult of Int32.
