我在单个XL文件中导出三张工作表。但我得到的工作表名称如Table1,Table2,Table3。
以下是没有调用数据库的C#代码,正确处理工作表名称。
var ds = new DataSet();
var dt = new DataTable("TableName For Sheet1");
dt.Columns.Add("col1");
dt.Columns.Add("col2");
dt.Rows.Add("Value1", "Value2");
var dt2 = new DataTable("TableName For Sheet2");
dt2.Columns.Add("col1");
dt2.Columns.Add("col2");
dt2.Rows.Add("Value1", "Value2");
ds.Tables.Add(dt);
ds.Tables.Add(dt2);
ExcelHelper.ToExcel(ds, "test.xls", Page.Response);
下面是用于调用数据库存储过程的C#代码,但是表名为Table1,Table2,Table2。
DataSe ds = new DataSet();
DataTable dt = new DataTable("Registration Details");
DataTable dt1 = new DataTable("Education Details");
DataTable dt2 = new DataTable("Employeement Details");
dt = bl.Get_Registrationdetailsbydate(bo);
gv_Regdetails.DataSource = dt;
gv_Regdetails.DataBind();
dt1 = bl.Get_Registrationdetailsbydate1(bo);
dt2 = bl.Get_Registrationdetailsbydate2(bo);
DataTable filteredEducation = dt1.AsEnumerable()
.Where(x => dt.AsEnumerable()
.Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))
.CopyToDataTable();
DataTable filteredEmployee = dt2.AsEnumerable()
.Where(x => dt.AsEnumerable()
.Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))
.CopyToDataTable();
ds.Tables.Add(dt);
ds.Tables.Add(filteredEducation);
ds.Tables.Add(filteredEmployee);
ExcelHelper.ToExcel(ds, "DangoteUsers.xls", Page.Response);
我需要工作表名称结果,如注册详情,教育详情和员工详细信息。

答案 0 :(得分:1)
初始化后,您将覆盖dt
,dt1
和dt2
,这就是为什么您没有正确获取名称而是获得表的默认名称。尝试在分配后为这三个表设置名称,或在分配逻辑中包含表名。我更新了您的代码以证明这一点。
DataSet ds = new DataSet();
var dt = bl.Get_Registrationdetailsbydate(bo);
gv_Regdetails.DataSource = dt;
gv_Regdetails.DataBind();
var dt1 = bl.Get_Registrationdetailsbydate1(bo);
var dt2 = bl.Get_Registrationdetailsbydate2(bo);
DataTable filteredEducation = dt1.AsEnumerable()
.Where(x => dt.AsEnumerable()
.Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))
.CopyToDataTable();
DataTable filteredEmployee = dt2.AsEnumerable()
.Where(x => dt.AsEnumerable()
.Any(z => z.Field<string>("Email").Trim() == x.Field<string>("Email").Trim()))
.CopyToDataTable();
dt.TableName = "Registration Details";
filteredEducation.TableName = "Education Details";
filteredEmployee.TableName = "Employeement Details";
ds.Tables.Add(dt);
ds.Tables.Add(filteredEducation);
ds.Tables.Add(filteredEmployee);
ExcelHelper.ToExcel(ds, "DangoteUsers.xls", Page.Response);
