我用下面的代码填写数据表 –

OleDbDataAdapter oleDA = new OleDbDataAdapter();
DataTable dt = new DataTable();
oleDA.Fill(dt, Dts.Variables["My_Result_Set"].Value); 

我收到错误 –

Error: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: Object is not an ADODB.RecordSet or an ADODB.Record.

为什么我会收到此错误？我之前使用过完全相同的代码,它从来没有给我任何问题.

解决方法:

在脚本任务中,我创建了一个名为DtUsers的数据表,在数据表中创建了列,为行单元格添加了行和赋值.然后我将这个数据表存储在一个名为activeDirectoryUsers的对象变量中：

Dts.Variables["User::activeDirectoryUsers"].Value = DtUsers;

然后我创建了一个数据流并添加了一个源脚本组件.我试图使用Fill()并收到与OP相同的错误.

OleDbDataAdapter da = new OleDbDataAdapter();
DataTable dt = new DataTable();
da.Fill(dt, Variables.activeDirectoryUsers);  //error here

Object is not an ADODB.RecordSet or an ADODB.Record

我的解决方案有两个方面：

>将DtUsers数据表添加到DataSet,然后将DataSet存储在对象变量中.

DataSet ds = new DataSet();
ds.Tables.Add(DtUsers);
Dts.Variables["User::activeDirectoryUsers"].Value = ds;

>在源脚本组件中,创建一个新的DataSet并将对象变量强制转换为类型DataSet,并将其分配给DataSet：

DataSet ds = (DataSet)Variables.activeDirectoryUsers;
if (ds == null || ds.Tables.Count == 0) return;
DataTable dt = ds.Tables[0];
//do stuff with dt...
