參數

• typeCode
  The system TypeCode to convert to the SSIS type.

傳回值

The SSIS type for the system TypeCode.

備註

For a list of the SSIS types, see Integration Services 資料類型.

The following table shows the TypeCode and what SSIS Variant data type they are converted to.

範例

The following example shows a pipeline component that overrides the RegisterEvents method and creates a custom event using the EventInfos collection, using the VarTypeFromTypeCode to create a reference type.

Public override void RegisterEvents()
{
string []parameters = new string[1]{"Parameter1"};
ushort []types = new ushort[1]{DtsConvert.VarTypeFromTypeCode(TypeCode.String)};
string []descriptions = new string [1]{"The first parameter."};

EventInfos.Add("OnPreExecute", "Fires when the PreExecute method runs.", false, ref parameters, ref types, ref descriptions);
}

Public Overrides  Sub RegisterEvents()
String ()parameters = New String(1)
{
    "Parameter1"
}

System.UInt16 ()types = New System.UInt16(1)
{
    DtsConvert.VarTypeFromTypeCode(TypeCode.String)
}

String ()descriptions = New String (1)
{
    "The first parameter."
}

 
EventInfos.Add("OnPreExecute", "Fires when the PreExecute method runs.", False,  parameters,  types,  descriptions)
End Sub
