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;
}
