尝试显示Excel工作表名称时SSIS中的运行时错误

Question

我尝试使用SSIS获取excel的工作表名称，因为工作表名称未知。但是我得到一些错误。

有人可以检查吗？我试图用Google搜索，但是找不到适用于我的案例的解决方案...

这是我的代码：

public void Main() {
    string excelFile = null;
    string connectionString = null;
    OleDbConnection excelConnection = null;
    DataTable tablesInFile = null;
    int tableCount = 0;
    DataRow tableInFile = null;
    string currentTable = null;
    int tableIndex = 0;
    string[] excelTables = null;

    excelFile = Dts.Variables["User::BBGFilePath"].Value.ToString();
    connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + excelFile + ";Extended Properties=Excel 8.0";
     excelConnection = new OleDbConnection(connectionString);
     excelConnection.Open();
     tablesInFile = excelConnection.GetSchema("Tables");
     tableCount = tablesInFile.Rows.Count;
     excelTables = new string[tableCount];

     foreach (DataRow tableInFile_loopVariable in tablesInFile.Rows) {
         tableInFile = tableInFile_loopVariable;
         currentTable = tableInFile["TABLE_NAME"].ToString();
         excelTables[tableIndex] = currentTable;
         tableIndex += 1;
     }

     Dts.Variables["User::SheetName"].Value = excelTables[0];
     string strMessage = Dts.Variables["User::SheetName"].Value.ToString();
     MessageBox.Show(strMessage);
     Dts.TaskResult = (int)ScriptResults.Success;
}

Answer 1

在我更改以下内容后，它现在可以工作：

1. 将ConnectionString更改为： ConnectionString =“ Provider = Microsoft.ACE.OLEDB.12.0; Data Source =” + excelFile +“;扩展属性= \” Excel 12.0; HDR = YES; IMEX = 0 \“”;

2. 在很多地方，“ ConnectionString”被写为“ connectionString”，而C＃似乎区分大小写？纠正它们后就可以了

谢谢大家！

Answer 2

请执行以下操作

ConnectionString =“ Provider = Microsoft.Jet.OLEDB.4.0; Data Source =” + excelFile +“;扩展属性= \” Excel 8.0; HDR =是; IMEX = 1 \“;”;

显示工作表名称

  

Foreach（可执行项中的变量项）{   Dts.Variables [“ User :: SheetName”]。Value = item.tosing（）;        字符串strMessage = Dts.Variables [“ User :: SheetName”]。Value.ToString（）;        MessageBox.Show（strMessage）;}

谢谢
