I'm trying to read an excel file into a dataset. I'm getting "Not a legal OleAut date.". I Googled it, and I don't see anything wrong with the data in the excel file.

Here's the code:

public DataSet ExcelToDataSet(string ExcelFile, string SheetName)
{
    DataSet ds = new DataSet();

    string ConnString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ExcelFile + ";Extended Properties=Excel 8.0;";

    OleDbConnection Conn = new OleDbConnection(ConnString);

    try
    {
        Conn.Open();
    }
    catch(Exception e)
    {
    }

    string Select = "SELECT * FROM [" + SheetName + "$]";
    OleDbCommand Command = new OleDbCommand(Select, Conn); 
    OleDbDataAdapter Adapter = new OleDbDataAdapter();
    Adapter.SelectCommand = Command;
    Adapter.Fill(ds); 
    
    Conn.Close();

    return ds;
}
