Type: System.Decimal
A Decimal.
d2
Type: System.Decimal
A Decimal.

Return Value

Type: System.Decimal
The Decimal result of adding d1 and d2.

ExceptionCondition
OverflowException

The return value is less than MinValue or greater than MaxValue.

The following code example creates several pairs of Decimal values and calculates their sums with the Addition operator.


// Example of the decimal addition and subtraction operators.
using System;

class Example
{
   const string dataFmt = "   {0,-18}{1,31}";

   // Display decimal parameters and their sum and difference.
   static void ShowDecimalSumDiff(System.Windows.Controls.TextBlock outputBlock, decimal Left, decimal Right)
   {
      outputBlock.Text += "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal Left", Left) + "\n";
      outputBlock.Text += String.Format(dataFmt, "decimal Right", Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "Left + Right",
          Left + Right) + "\n";
      outputBlock.Text += String.Format(dataFmt, "Left - Right",
          Left - Right) + "\n";
   }

   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      outputBlock.Text += "This example of the decimal " +
          "addition and subtraction operators \ngenerates the " +
          "following output. It displays the sum and \n" +
          "difference of several pairs of decimal objects." + "\n";

      // Create pairs of decimal objects.
      ShowDecimalSumDiff(outputBlock, 
          new decimal(1230000000, 0, 0, false, 7),
          0.0012300M);
