Convert::ToDecimal Method (String^)


Converts the specified string representation of a number to an equivalent decimal number.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

static Decimal ToDecimal(
	String^ value


Type: System::String^

A string that contains a number to convert.

Return Value

Type: System::Decimal

A decimal number that is equivalent to the number in value, or 0 (zero) if value is null.

Exception Condition

value is not a number in a valid format.


value represents a number that is less than MinValue or greater than MaxValue.

Using the ToDecimal(String^) method is equivalent to passing value to the Decimal::Parse(String^) method. value is interpreted by using the formatting conventions of the current thread culture.

If you prefer not to handle an exception if the conversion fails, you can call the Decimal::TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.

The following example illustrates the use of ToDecimal. It attempts to convert a Stringto a Decimal, and throws the possible exceptions that may arise during the conversion.

   void ConvertStringDecimal( String^ stringVal )
      Decimal decimalVal = 0;

         decimalVal = System::Convert::ToDecimal( stringVal );
         System::Console::WriteLine( "The String as a decimal is {0}.",
         decimalVal );
      catch ( System::OverflowException^ ) 
            "The conversion from String to decimal overflowed." );
      catch ( System::FormatException^ ) 
            "The String is not formatted as a decimal." );
      catch ( System::ArgumentNullException^ ) 
         System::Console::WriteLine( "The String is 0." );

      // Decimal to String conversion will not overflow.
      stringVal = System::Convert::ToString( decimalVal );
         "The decimal as a String is {0}.", stringVal );
