错误ExecuteReader：连接属性尚未初始化。在C＃脚本SSIS

Question

我收到此代码块中的错误，似乎无法找到问题。

SqlConnection con = (SqlConnection)(Dts.Connections["connection"].AcquireConnection(Dts.Transaction) as SqlConnection); 
ssqlRiskQuery = "My query"; 

using (SqlCommand command = new SqlCommand(ssqlRiskQuery, con)) 
{ 
    command.Connection = con; 
    using (SqlDataReader reader = command.ExecuteReader()) 
    { 
     while (reader.Read()) 
     { 
      OutputFileObjects.Add(reader["p.provider_id"].ToString(), new string[] { reader["bu.business_unit_id"].ToString(), reader["l.location_id"].ToString(), reader["cpd.claim_number"].ToString(), reader["v2.process_code"].ToString() }); 
     } 
    } 
} 
con.Close(); 

Answer 1

你需要connection.Open();

你还没有打开连接。
