MVC导入

1、点击导入按钮


2、 //打开dialog 与处理导入Excel

function ImportExcel()

{

$("#ImportExcel").show();

$("#ImportExcel").dialog({

title: "导入车型",

width: 1000,

height: 600,

draggable: true,

resizable: false,

modal: true,

buttons:

[

{

text: '保存',

iconCls: 'icon-save',

handler: function () {

var list = $("#ImportExcelCarTypeDT").datagrid("getRows");

AjaxCall("/BaseInfo/CarType/SaveImortExcel", { list: list }, function (res) {

if (res.ErrorCode == 1) {

$.messager.alert('提示', "保存成功!", 'info');

_rowIndex = 0;

GetCarType(_pageIndex, _pageSize);

}

else { $.messager.alert('提示', "保存失败!", 'error'); }

});

}

},

{

text: '取消',

handler: function () {

$("#ImportExcel").dialog('close');

}

}

]

});

}

3、点击导入



将数据发到控制器取操作

//利用nopi表单提交后导入excel

function ImportExcelByNPOI() {

$("#npoiload").form("submit", {

url: '/BaseInfo/CarType/ImportExcel/',

onSubmit: function () {},

success: function (data) { $('#ImportExcelCarTypeDT').datagrid('loadData', JSON.parse(data)); }

}

);

}

public object ImportExcel()

{

string errorMsg = "";

CarTypeBll bll = new CarTypeBll();

try

{

HttpPostedFileBase file = Request.Files["npoiload"];

Stream fs = file.InputStream;

IWorkbook wk = null;

try

{

wk = new HSSFWorkbook(fs);

}

catch (Exception ex)

{

wk = new HSSFWorkbook(fs);

}

ISheet st = wk.GetSheetAt(0);

int rowCount = st.LastRowNum;

List<EHECD_CarType> ct=new List<EHECD_CarType>();

List<EHECD_CarType> newct = new List<EHECD_CarType>();

List<EHECD_CarType> allct = bll.GetCarTypeImport();

for (int i = 1; i <= rowCount; i++)

{

EHECD_CarType cm = new EHECD_CarType();

cm.inportType = "";

cm.sFirstLetter = st.GetRow(i).GetCell(0).ToString();

cm.sBrand = st.GetRow(i).GetCell(1).ToString();

cm.sFirm = st.GetRow(i).GetCell(2).ToString();

cm.sModel = st.GetRow(i).GetCell(3).ToString();

cm.iYearsStyle = st.GetRow(i).GetCell(4).ToString();//100

if (!bll.HasChinese(st.GetRow(i).GetCell(8).ToString()))

{

cm.iGuidedPrice = Decimal.Parse(st.GetRow(i).GetCell(8).ToString());//18

}

else

{

cm.iGuidedPrice =0;

cm.inportType ="价格中有中文";

}

if (cm.sFirstLetter.Length > 10 )

{

cm.inportType = "首字母字段过长";

}

if (cm.sBrand.Length > 50 )

{

cm.inportType = "品牌字段过长";

}

if (cm.sFirm.Length > 50)

{

cm.inportType = "厂商字段过长";

}

if (cm.sModel.Length > 50)

{

cm.inportType = "型号字段过长";

}

if (cm.iYearsStyle.Length > 100 )

{

cm.inportType = "年代款型字段过长";

}

if (cm.sDisplacement.Length > 20)

{

cm.inportType = "排量字段过长";

}

if (cm.sTransmissionMmodel.Length > 50)

{

cm.inportType = "变速箱字段过长";

}

if (cm.sEngine.Length > 50)

{

cm.inportType = "发动机类型字段过长";

}

if (cm.sFirstLetter.Length == 0 || cm.sBrand.Length == 0 || cm.sFirm.Length == 0 || cm.sModel.Length == 0

|| cm.iYearsStyle.Length == 0 || cm.sDisplacement.Length == 0

|| cm.sTransmissionMmodel.Length == 0 || cm.sEngine.Length == 0)

{

cm.inportType = "字段不允许为空";

}

if (cm.inportType == "" || cm.inportType == null)

{

cm.inportType = "可正常导入";

}

////这里判断在数据库是否存在

if (cm.inportType== "可正常导入")

{

foreach (var item in allct)

{

if (cm.sFirstLetter == item.sFirstLetter && cm.sBrand == item.sBrand && cm.sFirm == item.sFirm && cm.sModel == item.sModel

&& cm.iYearsStyle == item.iYearsStyle && cm.sDisplacement == item.sDisplacement

&& cm.sTransmissionMmodel == item.sTransmissionMmodel && cm.sEngine == item.sEngine)

{

cm.inportType = "数据库已存在";

break;

}

}

}

ct.Add(cm);

}

newct = ct.Distinct(new CarTypeComparer()).ToList();

var result = new { total = newct.Count, rows = newct };

return MyJson.JsonSerializer(result);

}

catch (Exception ex)

{

errorMsg = "导入失败，请检查EXCEL格式" + ex.Message;

}

return Json(new {ErrorCode=2,ErrorMessage=errorMsg });

}
