DateTime AddMinutes() Method
The following ASp.NET C# example code demonstrates to us how can we add
minutes to a DateTime object programmatically at run time. The .Net
framework's DateTime AddMinutes() method allows us to add one or more minutes
with a DateTime object.
DateTime AddMinutes() method exists in the System namespace. AddMinutes() method has a required parameter named value. This value parameter data type is a Double which represents a number of whole and fractional minutes. This is very useful in that the value parameter value can be negative or positive. So, technically we can also subtract minutes from a DateTime object.
DateTime AddMinutes() method returns value data type is System.DateTime. This return value is a DateTime object which is the sum of specified minutes passed by the parameter and specified DateTime object. AddMinutes() method does not modify/change the provided DateTime object instead it returns a new DateTime object that is the result of this operation.
The DateTime AddMinutes() method through ArgumentOutOfRangeException exception if the resulting DateTime is less than MinValue or greater than MaxValue.
