存量報表有300張左右，如何批量添加?
需要添加登陸的工號和當前時間。

1：水印產生代碼using System;
using System.Data;
using System.Configuration;
using System.Drawing;
using System.Drawing.Imaging;

public class WatermarkCreater
{

{
//
// TODO: 在此加入建構函式的程式碼

}
private Bitmap CreateImage(string code, string width, string height, string pLeft, string pTop, string font, string fColor, string bColor, string r)
{
Color cF = Color.FromArgb(int.Parse(fColor.Substring(2, 2), System.Globalization.NumberStyles.AllowHexSpecifier), int.Parse(fColor.Substring(4, 2), System.Globalization.NumberStyles.AllowHexSpecifier), int.Parse(fColor.Substring(6, 2), System.Globalization.NumberStyles.AllowHexSpecifier));
Color cB = Color.FromArgb(int.Parse(bColor.Substring(2, 2), System.Globalization.NumberStyles.AllowHexSpecifier), int.Parse(bColor.Substring(4, 2), System.Globalization.NumberStyles.AllowHexSpecifier), int.Parse(bColor.Substring(6, 2), System.Globalization.NumberStyles.AllowHexSpecifier));
System.Drawing.SolidBrush sb = new SolidBrush(cF);
string[] fstr = font.Split(',');
Font f = new Font(fstr[0].Split('=')[1], (float)Convert.ToInt32(fstr[1].Split('=')[1]), FontStyle.Regular, (GraphicsUnit)Convert.ToInt32(fstr[2].Split('=')[1]), Convert.ToByte(fstr[3].Split('=')[1]), Convert.ToBoolean(fstr[4].Split('=')[1]));
Bitmap bmp = new Bitmap(Convert.ToInt32(width), Convert.ToInt32(height));
Graphics g = Graphics.FromImage(bmp);
g.Clear(Color.White);
g.RotateTransform((float)Convert.ToDouble(r));
g.DrawString(code, f, sb, new PointF(Convert.ToInt32(pLeft), Convert.ToInt32(pTop)));
return bmp;
}
public byte[] GetImageByte(string code, string config)
{
string[] configs = config.Split(';');
Bitmap im = CreateImage(code, configs[0].Split(':')[1], configs[1].Split(':')[1], configs[2].Split(':')[1], configs[3].Split(':')[1], configs[4], configs[5].Split(':')[1], configs[6].Split(':')[1], configs[7].Split(':')[1]);
System.IO.MemoryStream ms = new System.IO.MemoryStream();
im.Save(ms, ImageFormat.Bmp);
return ms.GetBuffer();
}
}
2：把水印保存到數據庫，數據庫類型為image
3:把水印查詢出來，作為數據源傳進報表，然後在報表的背景添加即可
