Question

c# 如何将图片信息从数据库中读取出来放入pictureBox1中:

Answer 1

要先判断图片数据是否为空
if(this.dataset.Tables[0].Rows[select]["照片信息"].ToString().Trim()!="")
{
int select = this.dataGrid.CurrentRowIndex; //获取选定行的索引值
MemoryStream mysm=new MemoryStream((byte [])this.dataset.Tables[0].Rows[select]["照片信息"]);
Image ims=Image.FromStream(mysm);
this.pictureBox1.Image=ims;
}
else //如果数据库中的图片数据为空,将pictureBox的image属性设置为空
{
System.Resources.ResourceManager resources = new System.Resources.ResourceManager(typeof(chufas));
this.pictureBox1.Image = ((System.Drawing.Image)(resources.GetObject(" ")));
}
