您好我正在使用json調用一個調用另一個函數，最終調用ExpotToExcel函數的函數。的功能是作爲以下導出到使用Json調用的函數不是以excel格式導出數據
$.ajax({
type: "post",
contentType: "application/json;charset=utf-8",
// dataType: "json",
url: "Model/Services/CurrentHistoryService.asmx/TestingExport",
data: JSON.stringify(empno),
success: function (resp) {
if (!(resp == null)) {
$('#ExportEmpInfo').empty();
$('#ExportEmpInfo').append('<p><b>' + 'Data Has been Exported to Excel successfully ' + '</b></p>');
}
else {
$('#ExportEmpInfo').empty();
$('#ExportEmpInfo').append('<p><b>' + 'Exporting to Excel Failed' + '</b></p>');
}
},
error: function (jqXHR, textStatus, errorThrown) {
alert('TextStatus:' + textStatus + ' errorThrown: ' + errorThrown);
}
})
的WebMethod：
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public void TestingExport(string empNo)
{
RefEmployeeRepository emply = new RefEmployeeRepository();
List<RefEmployee> empcurlist = emply.GetEmployeeCurrentByEMPNO(empNo);
DataTable dt = new DataTable();
dt = ToDataTable(empcurlist);
string title = "Customer Current Information";
ReferenceDataLogic.GenerateExcelReport(title, dt);
}
GenerateExcelReport功能：
public static void GenerateExcelReport(string value, DataTable localTable)
{
DataSet ds = new DataSet();
DataTable dtHeader = new DataTable();
dtHeader.Columns.Add(new DataColumn(value));
DataTable dtBlankRow = new DataTable();
dtBlankRow.Columns.Add(new DataColumn(" "));
ds.Tables.Add(dtHeader);
ds.Tables.Add(dtBlankRow);
ds.Tables.Add(localTable);
HelperFunctions.ExportToExcel(HttpContext.Current.Response, ds);
}
ExportToExcel功能：
public static void ExportToExcel(HttpResponse response, DataSet ds)
{
try
{
response.Clear();
response.ClearContent();
response.Charset = "";
response.ContentType = "application/vnd.ms-excel";
DataGrid dg = new DataGrid();
for (int i = 0; i < ds.Tables.Count; i++)
{
StringWriter stringWriter = new StringWriter();
HtmlTextWriter htmlWriter = new System.Web.UI.HtmlTextWriter(stringWriter);
stringWriter = new System.IO.StringWriter();
htmlWriter = new System.Web.UI.HtmlTextWriter(stringWriter);
dg.DataSource = ds.Tables[i];
dg.DataBind();
dg.RenderControl(htmlWriter);
response.Write(stringWriter.ToString());
}
response.Flush();
response.Close();
response.Write("");
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);
}
}
控制正在經歷所有這些功能但經過上次導出到Excel函數後不生成Excel文件。但是如果我直接使用另一個代碼背後的代碼來調用這個函數，而不是使用json來調用間接調用這個方法的web方法，那麼我會得到Excel工作表。請幫我解決這個問題，爲什麼在函數執行完成後出錯並沒有生成Excel表單。
