导入

（1）导入一张Excel表：



（图 1）



（图 2）

实现界面的代码：
<html>
<head>
<script src="../../Scripts/jquery-1.4.4.js" type="text/javascript"></script>
<script src="../../Scripts/jquery-1.4.4.min.js" type="text/javascript"></script>
<script type="text/javascript">
function daoru() {

window.location.href = "/Main/DownloadFile";
}

</script>
</head>
<body>
<input type="button" value="导出" onclick="daoru()"/>
<a href="/Main/ExportExcel">Click here</a>

<form action="/Main/GetTableFromExcel" method="post"  enctype="multipart/form-data">
//调用控制器的方法
<text>选择上传文件</text>
<input name="file1" type="file" id="file" />
<input type="submit" name="Upload" value="导入" />

</form>
</body>
</html>


调用控制器的方法：
#endregion
//导入
public ActionResult GetTableFromExcel()
{
HttpPostedFileBase fostFile = Request.Files["file1"];

Stream streamfile = fostFile.InputStream;

HSSFWorkbook hssfworkbook = new HSSFWorkbook(streamfile);
using (NPOI.SS.UserModel.ISheet sheet = hssfworkbook.GetSheetAt(0))
{
DataTable table = new DataTable();
IRow headerRow = sheet.GetRow(0);//第一行为标题行
int cellCount = headerRow.LastCellNum;//LastCellNum = PhysicalNumberOfCells
int rowCount = sheet.LastRowNum;//LastRowNum = PhysicalNumberOfRows - 1

//handling header.
for (int i = headerRow.FirstCellNum; i < cellCount; i++)
{
DataColumn column = new DataColumn(headerRow.GetCell(i).StringCellValue);
table.Columns.Add(column);
}
for (int i = (sheet.FirstRowNum + 1); i <= rowCount; i++)
{
IRow row = sheet.GetRow(i);
DataRow dataRow = table.NewRow();

if (row != null)
{
for (int j = row.FirstCellNum; j < cellCount; j++)
{
if (row.GetCell(j) != null)
dataRow[j] = GetCellValue(row.GetCell(j));
}
}

table.Rows.Add(dataRow);
}
for (int i = 0; i < table.Rows.Count; i++) {

myUpLoadBLL.ForDownLoad(table.Rows[i][1].ToString(), table.Rows[i][2].ToString(),Convert.ToBoolean( table.Rows[i][3]));
//调用逻辑层的方法
}
}

return Content("");
}
/// <summary>
/// 根据Excel列类型获取列的值
/// </summary>
/// <param name="cell">Excel列</param>
/// <returns></returns>
private static string GetCellValue(ICell cell)
{
if (cell == null)
return string.Empty;
switch (cell.CellType)
{
case CellType.BLANK:
return string.Empty;
case CellType.BOOLEAN:
return cell.BooleanCellValue.ToString();
case CellType.ERROR:
return cell.ErrorCellValue.ToString();
case CellType.NUMERIC:
case CellType.Unknown:
default:
return cell.ToString();
case CellType.STRING:
return cell.StringCellValue;
case CellType.FORMULA:
try
{
HSSFFormulaEvaluator e = new HSSFFormulaEvaluator(cell.Sheet.Workbook);
e.EvaluateInCell(cell);
return cell.ToString();
}
catch
{
return cell.NumericCellValue.ToString();
}
}
}


逻辑层的方法：
#region 导入

public int ForDownLoad(string Name,string Age,bool Gender)
{
//创建数组
SqlParameter[] sql ={
//实例化并传入参数和参数类型
new SqlParameter("@type",SqlDbType.Char),
new SqlParameter("@Name",SqlDbType.NVarChar),
new SqlParameter("@Age",SqlDbType.NVarChar),
new SqlParameter("@Gender",SqlDbType.Bit),
};
//为参数赋值
sql[0].Value = "ForDownLoad";
sql[1].Value = Name;
sql[2].Value = Age;
sql[3].Value = Gender;

//调用DAL方法连接数据库提取数据存放到数据表dt中
int count = myPublicMoth.UpdateData("ForUpLoadAndDownLoad", sql);
//返回dt
return count;
}
#endregion


数据层的SQL语句：
@type char(100)='',
@Name varchar(50)='',
@Age varchar(10)='',
@Gender bit=0
if(@type='ForDownLoad')
begin
Insert into Person(Name,Age,Gender)
VALUES(@Name,@Age,@Gender)
End
