Question

我需要读取一个excel文件，搜索每个值的ID并将这些值保存在数据库中： Excel original

这是我的代码：

int rowCount = 51,colCount = 11;
        Excel.Application xlApp = new Excel.Application();
        Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\Users\melissa\Desktop\lista_items.xlsx");
        Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1];
        Excel.Range xlRange = xlWorksheet.UsedRange;

for (int i = 2; i <= rowCount; i++)
        {
            item = xlRange.Cells[i, 1].Value2.ToString();
            id_color = consultas.buscar_color_codigo(xlRange.Cells[i, 2].Value2.ToString());
            id_fabricante = consultas.buscar_fabricante(xlRange.Cells[i, 3].Value2.ToString());
            id_size = consultas.buscar_talla(xlRange.Cells[i, 4].Value2.ToString());
            descripcion = xlRange.Cells[i, 5].Value2.ToString();
            id_body_type = consultas.buscar_body_type(xlRange.Cells[i, 6].Value2.ToString());
            id_gender = consultas.buscar_genero(xlRange.Cells[i,7].Value2.ToString());
            id_fabric_type = consultas.buscar_fabric_type(xlRange.Cells[i, 8].Value2.ToString());
            id_fabric_percent = consultas.buscar_percent(xlRange.Cells[i, 9].Value2.ToString());
            id_yarn = consultas.buscar_yarn(xlRange.Cells[i,10].Value2.ToString());
            division = xlRange.Cells[i, 11].Value2.ToString();}

要保存在数据库中：

 Conexion con_s = new Conexion();
            SqlCommand com_s = new SqlCommand();
            com_s.Connection = con_s.AbrirConexion();
            com_s.CommandText = " INSERT INTO items(item,id_color,id_fabricante,id_size,descripcion,id_body_type,id_gender,id_fabric_type,id_fabric_percent,id_yarn,division)VALUES" +
                "('" + item + "','" + id_color + "','" + id_fabricante + "','" + id_size + "','" + descripcion + "','" + id_body_type +
                "','" + id_gender + "','" + id_fabric_type + "','" + id_fabric_percent + "','" + id_yarn + "','" + division + "'  ) ";
            com_s.ExecuteNonQuery();
            con_s.CerrarConexion();

它仅搜索并保存10行，仅此而已。它没有显示任何错误，只是停止。我已经更改了httpRuntimeexecutionTimeout，仍然什么也没有。

任何帮助将不胜感激

在上传excel文件之前，请从excel的编辑标签中清除所有格式和注释等。它影响excel的UsedRange属性。如果您使用此行代码来获取上次使用的单元格和上一次使用的行，也会很有帮助。

int lastColumn = xlWorkSheet.LastColumnUsed().ColumnNumber();
int lastRow = xlWorkSheet.LastRowUsed().RowNumber();

希望有帮助。
