转：上传图片到服务器文件佳

以下是本在网站找的源码，希望对大家有点帮助：

Code

protected void btnAdd_Click(object sender, EventArgs e)//上传事件

{

bool fileOK = false;

string path = Server.MapPath("~/images/productPic/");//上传到服务器上的指定路径

if (FileUpload1.HasFile)//如果有上传文件，则判断文件类型

{

String fileExtension = System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();

String[] allowedExtensions = { ".gif", ".png", ".bmp", ".jpg" };

for (int i = 0; i < allowedExtensions.Length; i++)

{

if (fileExtension == allowedExtensions[i])

{

fileOK = true;

}

}

}

if (fileOK)

{

try

{

string timeStr = Convert.ToString(DateTime.Now.Year) + Convert.ToString(DateTime.Now.Month) + Convert.ToString(DateTime.Now.Day) + Convert.ToString(DateTime.Now.Hour) + Convert.ToString(DateTime.Now.Minute) + Convert.ToString(DateTime.Now.Second);//可以自己改，用于改变上传图片名称

FileUpload1.SaveAs(path + timeStr + FileUpload1.FileName);//将文件保存

//调用保存商品信息的方法，里面有一个参数是将商品图片路径保存到指定定段

bool succeed = cb.GoodsAdd_AddOneGood(this.txtGoodsName, this.txtGoodsType, this.txtGoodsAddress, "images/productPic/" + timeStr + FileUpload1.FileName, this.txt_Confine, this.txtGoodsColor, this.txtGoodsPrice, this.txtGoodsMaterial, this.txtGoodsModel, DateTime.Now);

if (succeed)

{

Response.Write("<script>alert('商品添加成功！')</script>");

}

else

{

Response.Write("<script>alert('商品添加失败！')</script>");

}

//这些注释了的语句在某些情况下可能会有用的。。

// LabMessage1.Text = "文件上传成功.";

// LabMessage2.Text = "<b>原文件路径：</b>" + FileUpload1.PostedFile.FileName + "<br />" +

// "<b>文件大小：</b>" + FileUpload1.PostedFile.ContentLength + "字节<br />" +

//"<b>文件类型：</b>" + FileUpload1.PostedFile.ContentType + "<br />";

}

catch (Exception ex)

{

// LabMessage1.Text = "文件上传不成功.";

Response.Write(cc.MessageBox("文件上传不成功"));

}

}

else

{

//LabMessage1.Text = "只能够上传图片文件.";

Response.Write(cc.MessageBox("只能够上传图片文件"));

}

}
