我有一个场景，我必须从未知的 excel 文件及其未知的选项卡中获取数据。所以我创建了一个有 50 列的表。
问题是进入第二个循环后 ssis 包没有进展。第一个循环获取文件名，第二个循环获取该文件中的选项卡名称。第二个循环中的 DTF 打开 excel 文件选项卡并读取数据并将其写入数据库表
我创建了一个单独的变量来存储从 foreach 循环容器中检索的文件名和选项卡名，并在 DTF 任务中使用它们。即使没有任何错误，DFT 任务也会被执行。
在 DFT 中，我只有一个脚本源来打开 excel 文件并读取数据，然后将其传递给 oledb 目标。
在厌倦了所有奇怪的事情之后，现在循环处理了 DFT 任务。在 DFT 上方的 foreach 循环中，我放置了一个脚本任务并弹出了一些测试。MessageBox.Show("blabla")。及其工作。现在怎么办？
下面是脚本任务中的代码。
public class ScriptMain : UserComponent
{
private OleDbDataReader excelReader;
private OleDbConnection excelConnection;
private OleDbCommand excelCommand;
public override void PreExecute()
{
base.PreExecute();
// Open
GetDataFromExcelToReader(Variables.IndividualFileNamesForDFT, Variables.IndividualTabNamesForDFT);
}
public override void PostExecute()
{
base.PostExecute();
excelReader.Close();
excelConnection.Close();
}
private void GetDataFromExcelToReader(string p_strFileName, string p_strTabName)
{
string l_strConnectionString;
if (File.Exists(p_strFileName))
{
string extension = Path.GetExtension(p_strFileName);
extension = extension.Replace(".", "");
if (extension.ToLower() == "xlsx")
{
l_strConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" +
"Data Source=" + p_strFileName + ";Extended Properties=\"Excel 12.0;HDR=NO;IMEX=1\";";
}
else
{
