C# TryParse() Safe convertion.

TryParse() - C# best practice

TryParse() is introduce In .Net framework 2.0 for safe conversion in string to any numismatic value. and its a replacement method of Parse which exist in earlier version of .net framework.

TryParse() has many advantages ;
Safe to convert string to many data types (int,decimal,float,byte,Boolean,double)
Not throw an exception if the conversion fails.
Return boolean if the conversion fails.
Handle the null conversion.

Why to use TryParse() instead of Parse();

Parse method will throw exception - ArgumentNullexception or FormatException or OverflowException, if the string value cannot be converted to the respective data type. so it will impact the system performance.

Explore the TryParse()

1:  int parsedResult;   
2:  int.TryParse("125A", out parsedResult); 

out put is

parsedResult =0

With more validation

string strTextData = "125A";
int parsedResult; 

if (int.TryParse(strTextData , out parsedResult))
{
   return "Valid Data";

}
else
{
 return "Invalid Data";
}
