속성

	이름	설명
	CreationName	Gets 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.
	DataType	Gets a TypeCode enumeration that describes the data type of the variable. This property is read-only.
	Description	Gets or sets the description for the variable.
	EvaluateAsExpression	Gets or sets a Boolean that indicates whether the variable contains an expression.
	Expression	Gets or sets the expression contained in a variable.
	ID	Gets the GUID assigned to the variable. This field is read-only.
	IncludeInDebugDump	Gets 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.
	Name	Gets or sets the name of the variable.
	Namespace	Gets or sets the namespace that the variable belongs to.
	Parent	Gets the parent container of the Variable instance.
	Properties	Gets a collection of DtsProperty objects. This property is read-only.
	QualifiedName	Gets the fully qualified name of the variable, including the namespace. This property is read-only.
	RaiseChangedEvent	Gets or sets a Boolean that indicates if the variable has been flagged to raise the OnVariableValueChanged event when the value of the variable changes.
	ReadOnly	Gets or sets a Boolean that indicates that the variable is read-only and cannot have its value modified.
	Site	인프라입니다. Gets or sets the site of the variable.
	SystemVariable	Gets a Boolean that indicates whether the variable is a system variable. This property is read-only.
	Value	Gets or sets the value assigned to the variable.

메서드

	이름	설명
	Dispose	This method is inherited from the IDisposable.Dispose method, which is a mechanism to explicitly tell an object to perform cleanup.
	Equals	Determines whether two object instances are equal. (DtsObject에서 상속됨)
	GetExecutionPath	Returns the execution path of the current Variable object.
	GetExpression	The GetExpression method is not supported on Variable objects. Use the EvaluateAsExpression property instead.
	GetHashCode	Returns the hash code for this instance. (DtsObject에서 상속됨)
	GetPackagePath	Returns the path of the package that the variable belongs to.
	GetSensitiveValue	Returns the sensitive variable value.
	GetType	(Object에서 상속됨)
	LoadFromXML	This method is not callable by your application code. Loads a package saved as .xml, use the Application.LoadPackage method.
	SaveToXML	This method is not callable by your application code. Saves a package as .xml, use the Application.SaveToXml method.
	SetExpression	The SetExpression method is not supported on Variable objects. Use the EvaluateAsExpression property instead.
	ToString	(Object에서 상속됨)

주의

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:

• IComponent

• IDisposable
