大家好我想将数据从dataset
导出到excel
表。我的dataset
由2 Tables
组成,那么如何在单个Excel工作表中编写多个数据集值
答案 0 :(得分:1)
1.使用Excel = Microsoft.Office.Interop.Excel; //在标题中,并添加正确的引用
2.Excel.Application excelHandle1 = PrepareForExport(Ds); //在调用函数中添加句柄
excelHandle1.Visible = true;
public Excel.Application PrepareForExport(System.Data.DataSet ds,string[] sheet)
{
object missing = System.Reflection.Missing.Value;
Excel.Application excel = new Excel.Application();
Excel.Workbook workbook = excel.Workbooks.Add(missing);
DataTable dt1 = new DataTable();
dt1 = ds.Tables[0];
DataTable dt2 = new DataTable();
dt2 = ds.Tables[1];
Excel.Worksheet newWorksheet;
newWorksheet = (Excel.Worksheet)excel.Worksheets.Add(missing, missing, missing, missing);
newWorksheet.Name ="Name of data sheet";
// for first datatable dt1..
int iCol1 = 0;
foreach (DataColumn c in dt1.Columns)
{
iCol1++;
excel.Cells[1, iCol1] = c.ColumnName;
}
int iRow1 = 0;
foreach (DataRow r in dt1.Rows)
{
iRow1++;
for (int i = 1; i < dt1.Columns.Count + 1; i++)
{
if (iRow1 == 1)
{
// Add the header the first time through
excel.Cells[iRow1, i] = dt1.Columns[i - 1].ColumnName;
}
excel.Cells[iRow1 + 1, i] = r[i - 1].ToString();
}
}
// for second datatable dt2..
int iCol2 = 0;
foreach (DataColumn c in dt2.Columns)
{
iCol2++;
excel.Cells[1, iCol] = c.ColumnName;
}
int iRow2 = 0;
foreach (DataRow r in dt2.Rows)
{
iRow2++;
for (int i = 1; i < dt2.Columns.Count + 1; i++)
{
if (iRow2 == 1)
{
// Add the header the first time through
excel.Cells[iRow2, i] = dt2.Columns[i - 1].ColumnName;
}
excel.Cells[iRow2 + 1, i] = r[i - 1].ToString();
}
}
return excel;
}

您可以在每张工作表中编写表值,而不是单个Excel工作表,

增加工作表计数,您可以在单个Excel文件中保存多个数据集值。
希望它对你有所帮助。
