メッセージボックスにExcelシート名を表示しようとしていますが、うまくいかないようです。誰か助けてください。
以下を追加するのにうんざりしましたが、何も表示されません。
string test = excelsheet.tostring();
messagebox.show(test);
私は本当にあなたの応答に感謝します。
前もって感謝します

The execution engine calls this method when the task executes.
To access the object model, use the Dts property. Connections, variables, events,
and logging features are available as members of the Dts property as shown in the following examples.
To reference a variable, call Dts.Variables["MyCaseSensitiveVariableName"].Value;
To post a log entry, call Dts.Log("This is my log text", 999, null);
To fire an event, call Dts.Events.FireInformation(99, "test", "hit the help message", "", 0, true);
To use the connections collection use something like the following:
ConnectionManager cm = Dts.Connections.Add("OLEDB");
cm.ConnectionString = "Data Source=localhost;Initial Catalog=AdventureWorks;Provider=SQLNCLI10;Integrated Security=SSPI;Auto Translate=False;";
Before returning from this method, set the value of Dts.TaskResult to indicate success or failure.
To open Help, press F1.
