export data table to word table

[shulamit.adler]

Hi,
i copy the following code from the examles:
private void Button_Click(object sender, RoutedEventArgs e)
{
Spire.DataExport.RTF.RTFExport rtfExport = new Spire.DataExport.RTF.RTFExport()
rtfExport.DataSource = Spire.DataExport.Common.ExportSource.DataTable;
rtfExport.DataTable = dt;
rtfExport.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView;
RTFStyle rtfStyle = new RTFStyle();
rtfStyle.FontColor = System.Drawing.Color.Blue;
rtfStyle.BackgroundColor = System.Drawing.Color.LightGreen;
rtfExport.RTFOptions.DataStyle = rtfStyle;
rtfExport.FileName = @"..\..\ToWord.doc";
rtfExport.SaveToFile();
}

the line :
Spire.DataExport.RTF.RTFExport rtfExport = new Spire.DataExport.RTF.RTFExport()
throw an exception:
An unhandled exception of type 'System.ArgumentException' occurred in mscorlib.dll

Additional information: Source array was not long enough. Check srcIndex and length, and the array's lower bounds.

the stackTrace is:

Dear shulamit.adler,

Thanks for your inquiry.
I have tested your scenario with the latest Spire.DataExport for .NET (Hot Fix) Version:3.5.86. But I didn't find there is any issue, please try to use this version. And after trying, if your issue still perests, please provide us your data.
Here is my testing code for your kind reference:

Code: Select all

            DataTable dt = new DataTable();
            dt.Columns.Add("test", typeof(string));
            for (int i = 0; i < 100; i++)
            {
                dt.Rows.Add("test");
            }
            Spire.DataExport.RTF.RTFExport rtfExport = new Spire.DataExport.RTF.RTFExport();
            rtfExport.DataSource = Spire.DataExport.Common.ExportSource.DataTable;
            rtfExport.DataTable = dt;
            rtfExport.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView;
            RTFStyle rtfStyle = new RTFStyle();
            rtfStyle.FontColor = System.Drawing.Color.Blue;
            rtfStyle.BackgroundColor = System.Drawing.Color.LightGreen;
            rtfExport.RTFOptions.DataStyle = rtfStyle;
           rtfExport.FileName = @"result.doc";
           rtfExport.SaveToFile();

Sincerely,
Betsy
