示例

以下代码示例展示了当数据流组件有两个输出属于同一排除组且同步输入相同时，该性质的 ExclusionGroup 使用方式。

public override void ProvideComponentProperties()  
{  
    IDTSInput100 input = ComponentMetaData.InputCollection.New();  
    Input.Name = "DTSSampleInput";  

    IDTSOutput output = ComponentMetaData.OutputCollection.New();  
    output.ExclusionGroup = 1;  
    output.Name = "Output1";  
    output.SynchronousInputID = input.ID;  

    IDTSOutput output = ComponentMetaData.OutputCollection.New();  
    output.ExclusionGroup = 1;  
    output.Name = "Output2";  
    output.SynchronousInputID = input.ID;  
}  
public override void ProcessInput(int inputID, PipelineBuffer buffer)  
{  
    IDTSInput100 input = ComponentMetaData.InputCollection.GetObjectByID(inputID);  

    IDTSOutput100 output1 = ComponentMetaData.OutputCollection[0];  
    IDTSOutput100 output2 = ComponentMetaData.OutputCollection[1];  

    while( buffer.NextRow())  
    {  
        // If criteria is met, direct the buffer row to output1.  
        buffer.DirectRow(output1.ID);  
        // Otherwise, direct the row to output2.  
        buffer.DirectRow(output2.ID);  
    }  
}  

Public  Overrides Sub ProvideComponentProperties()   
 Dim input As IDTSInput100 = ComponentMetaData.InputCollection.New   
 Input.Name = "DTSSampleInput"   
 Dim output As IDTSOutput = ComponentMetaData.OutputCollection.New   
 output.ExclusionGroup = 1   
 output.Name = "Output1"   
 output.SynchronousInputID = input.ID   
 Dim output As IDTSOutput = ComponentMetaData.OutputCollection.New   
 output.ExclusionGroup = 1   
 output.Name = "Output2"   
 output.SynchronousInputID = input.ID   
End Sub   

Public  Overrides Sub ProcessInput(ByVal inputID As Integer, ByVal buffer As PipelineBuffer)   
 Dim input As IDTSInput100 = ComponentMetaData.InputCollection.GetObjectByID(inputID)   
 Dim output1 As IDTSOutput100 = ComponentMetaData.OutputCollection(0)   
 Dim output2 As IDTSOutput100 = ComponentMetaData.OutputCollection(1)   
 While buffer.NextRow   
   buffer.DirectRow(output1.ID)   
   buffer.DirectRow(output2.ID)   
 End While   
End Sub  

注解

ExclusionGroup当两个输出同步到同一IDTSInput100对象，并且你想将行专门指向一个输出或另一个时，该属性就被设置了。 两个输出的属性ExclusionGroup和属性值必须相同SynchronousInputID。 如果你想使用排除群，必须将该属性设置为非零值;否则，保持默认值为零。

在执行过程中，具有多个输出且具有相同同步输入和相同非零排除组的数据流组件，会使用DirectRow该方法将输入PipelineBuffer的行直接发送到其中一个输出，或者当属性IsErrorOut为 true时，则该方法。DirectErrorRow
