下面附上 Excel Used Excel

   //Establish a Connection
            string XlxPath = @"C:\Users\BreakIn\Documents\Visual Studio 2010\Projects\Test\TestData\Test Data.xlsx";
            string XlxPathCon = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + XlxPath + ";Extended Properties=Excel 8.0;HDR=Yes'";
            OleDbCommand MyDataAdp = new OleDbCommand();
            OleDbConnection Xlxconn = new OleDbConnection(XlxPathCon);
            MyDataAdp.Connection = Xlxconn;

          //  Accessing Sheets
            Xlxconn.Open();
            DataTable xdt;
            // Get all Sheets in Excel File
            xdt = Xlxconn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
            Xlxconn.Close();

            DataSet ds = new DataSet();
            String SheetName = xdt.Rows[0]["TABLE_NAME"].ToString();
            MyDataAdp.CommandText = "SELECT Test From[" + SheetName + "]";

            OleDbDataAdapter da = new OleDbDataAdapter(MyDataAdp);
            da.SelectCommand = MyDataAdp;
            da.Fill(ds);

            Testdes.Items.Clear();
            foreach (DataRow value in xdt.Rows)

            {
                Testdes.DataSource = ds.Tables["SheetName"].Columns["test"];
                Testdes.Items.Add(value["test"]);
            }
           Testdes.SelectedIndex = 0;
        }
    }
}

}

其中“Testdes”是组合框。

如何将 Excel 中特定行中“C”列的值放入 ComboBox。

Answer 1

您确定没有错误吗？ 您的扩展属性的开头引号似乎丢失了

";Extended Properties=Excel 8.0;HDR=Yes'";

应该是：

";Extended Properties='Excel 8.0;HDR=Yes'";
