备注
This method is called when a component is first added to a data flow task. It is similar to a constructor and is the method that initializes a component. Components should add their inputs, outputs, and custom properties during this method.
The base class adds synchronous IDTSInput90 and IDTSOutput90 object to the ComponentMetaData.
For more information, see Design-time Methods of a Data Flow Component.
示例
public override void ProvideComponentProperties()
{
// Reset the component.
base.RemoveAllInputsOutputsAndCustomProperties();
IDTSInput90 input = ComponentMetaData.InputCollection.New();
input.Name = "Input";
IDTSOutput90 output = ComponentMetaDAta.OutputCollection.New();
output.Name = "Output";
output.SynchronousInputID = input.ID;
IDTSCustomProperty90 property = ComponentMetaData.CustomPropertyCollection.New();
property.Name = "RuntimeVariable";
property.Description = "Identifies a Variable in the package.";
}
Public Overrides Sub ProvideComponentProperties()
MyBase.RemoveAllInputsOutputsAndCustomProperties
Dim input As IDTSInput90 = ComponentMetaData.InputCollection.New
input.Name = "Input"
Dim output As IDTSOutput90 = ComponentMetaDAta.OutputCollection.New
output.Name = "Output"
output.SynchronousInputID = input.ID
Dim property As IDTSCustomProperty90 = ComponentMetaData.CustomPropertyCollection.New
property.Name = "RuntimeVariable"
property.Description = "Identifies a Variable in the package."
