I am using oledb to read data from an excel file and store it in a dataset. My excel file contents are like as follows:
0 0 somestring somestring
500 200 somestring somestring
When i checked the contents of my data set, the values of Columns 1 & 2 are not stored as integers but rather as DateTime values.
How will I make it be stored as integer values instead of DateTime?
您是否尝试将IMEX = 1添加到OLEDB连接字符串?
Are you sure its a number? Following could be a few options:
that is,
Excel.Worksheet sheet = this.Application.ActiveSheet as Excel.Worksheet;
Excel.Range range = sheet.get_Range("A1", "A5") as Excel.Range;
//delete previous validation rules
range.Validation.Delete();
You could use a 3rd party component like SpreadsheetGear for .NET which lets you get the underlying values of cells (with IWorkbook.Worksheets["MySheet"].Cells[rowIndex, colIndex].Value) regardless of the cell format, or you can get the formatted result with IRange.Text.
You can see live ASP.NET samples here and download the free trial here .
