public sealed class Variable : DtsObject, 
	IDTSPersist, IDTSName, IDTSPropertiesProvider, IDTSPackagePath, IComponent, 
	IDisposable

The Variable type exposes the following members.

  NameDescription
Public propertyCreationNameReturns the string that the runtime engine gives when it creates an instance of the Variable object and adds the object to the Variables collection. This property is read-only.
Public propertyDataTypeReturns a TypeCode enumeration that describes the data type of the variable. This property is read-only.
Public propertyDescriptionGets or sets the description for the variable.
Public propertyEvaluateAsExpressionGets or sets a Boolean that indicates that the variable contains an expression.
Public propertyExpressionGets or sets the expression contained in a variable.
Public propertyIDThe GUID assigned to the variable. This field is read-only.
Public propertyIncludeInDebugDumpGets or sets a value that specifies whether the variable value for a user-defined variable or a system variable is included in the debug dump files.
Public propertyNameGets or sets the name of the variable.
Public propertyNamespaceGets or sets the namespace that the variable belongs to.
Public propertyPropertiesReturns a collection of DtsProperty objects. This property is read-only.
Public propertyQualifiedNameGets the fully qualified name of the variable, including the namespace. This property is read-only.
Public propertyRaiseChangedEventA Boolean that indicates if the variable has been flagged to raise the OnVariableValueChanged event when the value of the variable changes.
Public propertyReadOnlyGets or sets a Boolean that indicates that the variable is read-only and cannot have its value modified.
Public propertySiteInfrastructure.
Public propertySystemVariableReturns a Boolean that indicates if the variable is a system variable. This property is read-only.

Public methodEqualsDetermines whether two object instances are equal. (Inherited from DtsObject.)
Protected methodFinalize (Inherited from Object.)
Public methodGetExpressionThe GetExpression method is not supported on Variable objects. Use the EvaluateAsExpression property instead.
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from DtsObject.)
Public methodGetPackagePathReturns the path of the package that the variable belongs to.
Public methodGetType (Inherited from Object.)
Public methodLoadFromXMLThis method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
Protected methodMemberwiseClone (Inherited from Object.)
Public methodSaveToXMLThis method is not callable by your application code. To save a package as .xml, use the Application.SaveToXml method.

Variables are grouped into namespaces for disambiguation. The System namespace is created automatically for every package and contains read-only properties. The User namespace contains custom properties that you can add. You can also create a namespace of your choosing to which to add variables. This class inherits from several classes and interfaces, including two from the Visual Studio .NET Framework:

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
