属性

  名称 说明
公共属性 CollectionEnumerator Gets or sets Boolean that indicates if the foreach loop enumerator is enumerating collections of objects or enumerating collections of collections. (从 ForEachEnumerator 继承。)
公共属性 Connection Gets or sets a String that contains the connection information for the schema rowset enumerator.
公共属性静态成员 ForEachEnumeratorDescription Returns a description for the ForEachSchemaRowsetEnumerator.
公共属性静态成员 ForEachEnumeratorDisplayName Gets or sets a String that contains the display name for the enumerator.
公共属性 Restrictions Gets or sets an array of Strings that contains the restrictions to apply to the rowset that is returned.
公共属性 SchemaRowset Gets or sets the GUID of the schema
公共属性 Version Returns the version number of the package. This property is read-only. (从 ForEachEnumerator 继承。)

方法

  名称 说明
公共方法 CanUpdate A Boolean that indicates if the new package XML can update the old package XML. (从 ForEachEnumerator 继承。)
公共方法 Equals Determines whether two object instances are equal. (从 DtsObject 继承。)
受保护方法 Finalize (从 Object 继承。)
公共方法 GetEnumerator Returns an enumerator for iterating over the collection. (覆盖 ForEachEnumerator. . :: . .GetEnumerator(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging)。)
公共方法 GetHashCode Returns the hash code for this instance. (从 DtsObject 继承。)
公共方法 GetType (从 Object 继承。)
公共方法 InitializeForEachEnumerator Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (从 ForEachEnumerator 继承。)
公共方法 LoadFromXML This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method.
受保护方法 MemberwiseClone (从 Object 继承。)
公共方法 SaveToXML This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method.
公共方法 ToString (从 Object 继承。)
公共方法 Update This method updates the old package XML with the new package XML if CanUpdate is set to true. (从 ForEachEnumerator 继承。)
公共方法 Validate Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (从 ForEachEnumerator 继承。)
