I am using Spire.DataExport.DBF.DBFExport to export a DataTable to a .DBF file. Several columns in the DataTable are columns that only contain values of type INT.

Using C# and .NET 4.5 it seems when I export a column of type INT to a .DBF file the output value is formated as a NUMERIC of 15 digits with 4 decimal point precision. How do I instruct Spire.DataExport.DBF.DBFExport to treat that column as an INT?

Thank you for any assistance in this matter.

Hello,

Thanks for your inquiry.
After an initial test with the latest Spire.Office Platinum (DLL Only) Version:3.10.3, I didn't reproduce the issue that the INT type was formatted after exporting to .dbf. Attached is my generated .dbf. If you were using an old version, I suggest that you upgrade to the latest version to have a test, if the issue still happens, please provide your code as well as your output .dbf file for our reference.
My testing code:
Code: Select all
private void LoadData_Click(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    dt.Columns.Add("column1", typeof(int));
    dt.Columns.Add("column2", typeof(int));
    DataRow row = dt.NewRow();
    row[0] = "1000";
    row[1] = "2000";
    dt.Rows.Add(row);

    this.dataGridView1.DataSource = dt;
}
private void ExportToDBF_Click(object sender, EventArgs e)
{
    Spire.DataExport.DBF.DBFExport DBFExport = new Spire.DataExport.DBF.DBFExport();
    DBFExport.DataSource = Spire.DataExport.Common.ExportSource.DataTable;
    DBFExport.DataTable = this.dataGridView1.DataSource as DataTable;
    DBFExport.ActionAfterExport = Spire.DataExport.Common.ActionType.OpenView;
    DBFExport.FileName = "result.dbf";
    DBFExport.SaveToFile();
}
