Eigenschaften
Name | Beschreibung | |
---|---|---|
CollectionEnumerator | Gets or sets Boolean that indicates if the foreach loop enumerator is enumerating collections of objects or enumerating collections of collections. (Geerbt von ForEachEnumerator.) | |
Connection | Gets or sets a String that contains the connection information for the schema rowset enumerator. | |
ForEachEnumeratorDescription | Returns a description for the ForEachSchemaRowsetEnumerator. | |
ForEachEnumeratorDisplayName | Gets or sets a String that contains the display name for the enumerator. | |
Restrictions | Gets or sets an array of Strings that contains the restrictions to apply to the rowset that is returned. | |
SchemaRowset | Gets or sets the GUID of the schema | |
Version | Returns the version number of the package. This property is read-only. (Geerbt von ForEachEnumerator.) |

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