我如何填写excel listobject表中的数据表

我的主要问题是从Excel电子表格中的列表对象中获取信息。 由于某种原因，它不会将string转换为int，看看我已经评论。 任何帮助将不胜感激。

public static DataTable excelDerivedAssembliesDT(string excelDir, int jobID) { DataTable dt = new DataTable(); var excelApp = new Excel.Application(); try { excelApp.Visible = false; excelApp.Workbooks.Open(excelDir); Excel.ListObject vstoListObject = excelApp.Worksheets[1].ListObjects[1];  DataColumn assemblyID = new DataColumn(); assemblyID.DataType = System.Type.GetType("System.Int32"); assemblyID.ColumnName = "assemblyID"; assemblyID.AutoIncrement = true; dt.Columns.Add(assemblyID); DataColumn assemblyNo = new DataColumn(); assemblyNo.DataType = System.Type.GetType("System.Int32"); assemblyNo.ColumnName = "assemblyNo"; dt.Columns.Add(assemblyNo); DataColumn job = new DataColumn(); job.DataType = System.Type.GetType("System.Int32"); job.ColumnName = "jobID"; dt.Columns.Add(job); DataColumn assemQTY = new DataColumn(); assemQTY.DataType = System.Type.GetType("System.Int32"); assemQTY.ColumnName = "assemblyQty"; dt.Columns.Add(assemQTY); DataRow dataRow = dt.NewRow();    foreach (Excel.ListRow row in vstoListObject.ListRows) {  //This is the part i cant seem to get to work i just cant see why it shouldn't  dataRow["assemblyNo"] = (int)(row.Range.Cells[1, 1]).ToString()); dataRow["assemblyQty"] = (int)(row.Range.Cells[1, 2]).ToString()); dataRow["jobID"] = (int)(row.Range.Cells[1, 3]).ToString()); dt.Rows.Add(dataRow); dataRow = dt.NewRow(); } dt.AcceptChanges(); } catch(exception e) { MessageBox.Show(e.ToString()); } return dt; } 

提前致谢。

你正试图把一个string转换成一个整数，这将引发一个exception。 你应该使用

 int.Parse((row.Range.Cells[1, 1]).ToString())
