Data Types

The following tables describe some common data types used in Workflow Designer. These data types apply to variables and arguments.

The following table contains the most frequently used data types. These types are listed in many of the Workflow Designer's drop-down lists, so you can select them from the list.

Common Data Types that are Listed in Workflow Designer Drop-Down Lists

System.Array of [T]

An array is a sequential list of items. The type of items you can store in the array are defined by the type of the array at declaration. Arrays can be single or multi-dimensional, and each dimension can have varying lengths (jagged). List(T) is more flexible when dealing with collections of items.

More information: System.Array

System.Boolean

Can take one of two values: True or False.

More information: System.Boolean

System.DateTime

The date data type.

More information: System.DateTime

System.Double

A Double is a number that includes a fraction, so any decimal value. Currency variables use this data type.

More information: System.Double

System.Exception

Represents errors that occur during application execution.

More information: System.Exception

System.Int32

Integers are whole numbers, that is, numbers that do not have a fractional part, like .7 or .34. Possible values are -32767 to 32767.

More information: System.Int32

System.Object

Supports all classes in the .NET Framework class hierarchy and provides low-level services to derived classes. This is the ultimate base class of all classes in the .NET Framework—it is the root of the type hierarchy.

More information: System.Object

System.String

A string is a sequence of characters. For example: string a = "This is a string";

Strings must be enclosed in double quotes, except for in Form Designer. Double quotes cannot occur inside double quotes unless they are escaped.

More information: System.String
