FastReport实现绑定图片信息

第一步：C#定义用于FastReport绑定的图片路径属性

[NotMapped]
public string SignatureImgPath { get; set; }

第二步：SignatureImgPath 路径生成图片

第三步：FastReport模板创建，添加PictureBox

　　注：添加普通文本绑定SignatureImgPath 属性

第四步：实现数据加载绑定

private void Data1_BeforePrint(object sender, EventArgs e)
    {
      string img = Report.GetColumnValue("one.SignatureImgPath").ToString();
      Picture1.ImageLocation=img;
    }

　

 注：隐藏SignatureImgPath 文本框(即图片路径)
