{
System.Drawing.Font drawFont = new System.Drawing.Font("Arial", 16);
SizeF size = finalImage.MeasureString(sDraw, drawFont);
Matrix mx = new Matrix(1, 0, 0, 1, 0, 0);
mx.Rotate(315, MatrixOrder.Append);
mx.Translate(thumbImage.Width / 2, thumbImage.Height / 2, MatrixOrder.Append);
finalImage.Transform = mx;
SolidBrush drawBrush = new SolidBrush(System.Drawing.Color.Black);
finalImage.DrawString(sDraw, drawFont, drawBrush, -size.Width / 2, -size.Height / 2, StringFormat.GenericTypographic);
}
finalImage.Dispose();
thumbImage.Save(@"c:\NewImage.jpg");
}
catch (Exception ex)

Yes this code can add the text on image. simply fill your text in sDraw variable. The text will be added as a watermark. For adding text at other directions change the matrix used.

remove the lines mx.Rotate(315, MatrixOrder.Append); and
mx.Translate(thumbImage.Width / 2, thumbImage.Height / 2, MatrixOrder.Append);
Add the line mx.Translate(0, 0, MatrixOrder.Append);
