示例

以下示例调用 ReinitializeMetaData 以响应组件验证失败。

Dim p As Package = New Package   
Dim dataFlow As MainPipe = CType(CType(p.Executables.Add("DTS.Pipeline"), TaskHost).InnerObject, MainPipe)   
Dim md As IDTSComponentMetaData100 = dataFlow.ComponentMetaDataCollection.New   
md.ComponentClassID = "DTSAdapter.OleDbSource"   
Dim wrp As CManagedComponentWrapper = md.Instantiate   
wrp.ProvideComponentProperties  

If wrp.Validate = DTSValidationStatus.VS_NEEDSNEWMETADATA Then   
 wrp.ReinitializeMetaData   
End If  

Package p = new Package();  
MainPipe dataFlow = ((TaskHost)p.Executables.Add("DTS.Pipeline")).InnerObject as MainPipe;  

IDTSComponentMetaData100 md = dataFlow.ComponentMetaDataCollection.New();  
md.ComponentClassID = "DTSAdapter.OleDbSource";  
CManagedComponentWrapper wrp = md.Instantiate();  
wrp.ProvideComponentProperties();  

if (wrp.Validate() == DTSValidationStatus.VS_NEEDSNEWMETADATA)  
{  
    wrp.ReinitializeMetaData();  
}  

注解

调用 ReinitializeMetaData 方法以响应从 Validate 返回VS_NEEDSNEWMETADATA的组件。 在此方法期间，如果组件可以修复验证中标识的任何错误，则组件会修复这些错误。
