I want DataGridview details to be exported as Word file.

Question

I am using Spire.Doc to export datagridview data to word, i am using below code, the problem is dont want to declare the array size it should be auto calculated as per the Rows of the Datagridview

 

Can anyone help me on the below where i can later add more than 1 Datagridview details also....

using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
Document doc = new Document();
Section section = doc.AddSection();
Spire.Doc.Table table3 = section.AddTable(true);
String[] Header3 = { "Column1", "Column2" };
String[][] data3 = new String[4][];
for (int k = 0; k < 4; k++)
{
data3[k] = new string[this.DataGridView.ColumnCount];
for (int j = 0; j < this.DataGridView.ColumnCount; j++)
{
data3[k][j] = this.DataGridView.Rows[k].Cells[j].Value.ToString();
}
}
//Add Cells
table3.ResetCells(data3.Length + 1, Header3.Length);
table3.TableFormat.Borders.Horizontal.LineWidth = 1;
table3.TableFormat.Borders.Vertical.LineWidth = 1;
//Header Row
Spire.Doc.TableRow FRow3 = table3.Rows[0];
FRow3.IsHeader = true;
//Row Height
FRow3.Height = 23;
for (int i = 0; i < Header3.Length; i++)
{
//Cell Alignment
Paragraph p1 = FRow3.Cells[i].AddParagraph();
FRow3.Cells[i].CellFormat.VerticalAlignment = VerticalAlignment.Middle;
p1.Format.HorizontalAlignment = Spire.Doc.Documents.HorizontalAlignment.Center;
//Data Format
TextRange TR = p1.AppendText(Header3[i]);
TR.CharacterFormat.FontName = "Century Gothic";
TR.CharacterFormat.FontSize = 13;
//TR.CharacterFormat.TextColor = Color.Teal;
TR.CharacterFormat.Bold = true;
}
//Data Row
for (int r = 0; r < data3.Length; r++)
{
Spire.Doc.TableRow DataRow = table3.Rows[r + 1];
//Row Height
DataRow.Height = 20;
//C Represents Column.
for (int c = 0; c < data3[r].Length; c++)
{
//Cell Alignment
DataRow.Cells[c].CellFormat.VerticalAlignment = VerticalAlignment.Middle;
//Fill Data in Rows
Paragraph p2 = DataRow.Cells[c].AddParagraph();
TextRange TR2 = p2.AppendText(data3[r][c]);
//Format Cells
p2.Format.HorizontalAlignment = Spire.Doc.Documents.HorizontalAlignment.Center;
TR2.CharacterFormat.FontName = "Century Gothic";
TR2.CharacterFormat.FontSize = 12;
//TR2.CharacterFormat.TextColor = Color.Brown;
}
}
doc.SaveToFile("OperateWord.docx", FileFormat.Docx);
System.Diagnostics.Process.Start("OperateWord.docx");
