Question

我正在尝试在自定义PipelineComponent

中读取包变量

public override void PreExecute()
{
            IDTSVariable100 vars2 = null;
            VariableDispenser.LockForRead("System::databse");
            VariableDispenser.GetVariables(out vars2);
}

VariableDispenser.GetVariables（out vars2）给了我错误

"The best overloaded method match for 
"Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariableDispenser100.GetVariables(out Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSVariables100)' 
 has some invalid argument.

Answer 1

嗯，除了IDTSVariableDispenser100接口是“supports the SQL Server infrastructure and is not intended to be used directly from your code”的API之一这一事实外，您已声明vars2的类型错误。 IDTSVariableDispenser100.GetVariables方法采用类型为out的{{1}}参数，而不是IDTSVariables100。（注意“s”。）
