using Excel = Microsoft.Office.Interop.Excel;
您显然需要将引用添加到您的项目中,然后就很简单了:)
You'll obviously need to add the reference to your project, and then it's plain simple :)
private void ProcessExcel(string filepath)
{
Excel.ApplicationClass ExcelObj = new Excel.ApplicationClass();
Excel.Workbook theWorkbook = ExcelObj.Workbooks.Open(filepath, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
Excel.Sheets sheets = theWorkbook.Worksheets;
Excel.Worksheet worksheet = (Excel.Worksheet)sheets.get_Item(1);
Excel.Range range = worksheet.UsedRange;
System.Array myvalues = (System.Array)range.Cells.Value2;
int vertical = myvalues.GetLength(0);
int horizontal = myvalues.GetLength(1);
string[] headers = new string[horizontal];
string[] data = new string[horizontal];
DataTable ResultsHeader = New DataTable();
DataSet ds = New DataSet();
for (int x = 1; x <= vertical; x++)
{
Utils.inicializarArrays(datos);
for (int y = 1; y <= horizontal; y++)
{
if (x == 1)
{
headers[y - 1] = myvalues.GetValue(x, y).ToString();
}
else
{
string auxdata = "";
if (myvalues.GetValue(x, y) != null)
auxdata = myvalues.GetValue(x, y).ToString();
data[y - 1] = auxdata;
}
}
if(x == 1) //headers
{
for(int w = 0; w < horizontal; w++)
{
ResultsHeader.Columns.Add(New DataColumn(headers[w], GetType(string)));
}
ds.Tables.Add(ResultsHeader);
}
else
{
DataRow dataRow = ds.Tables[0].NewRow();
for(int w = 0; w < horizontal; w++)
{
dataRow(headers[w]) = data[w]
}
ds.Tables[0].Rows.Add(dataRow);
}
}
DataView myDataView = new DataView();
myDataView.Table = ds.Tables[0];
MydataGrid.CurrentPageIndex = 0;
MydataGrid.DataSource = myDataView;
MydataGrid.DataBind();
}
