㈥ 在C#中，如何实现上传图像的功能……
参考代码如下：string filepath = FileUpload1.PostedFile.FileName;
string filename = filepath.Substring(filepath.LastIndexOf( "\\ "));
string fileEx = filepath.Substring(filepath.LastIndexOf( ". ")+1);
string serverpath = "C:/aa/upload/ " + filename;
string dbpath = "\\upload\\ " + filename;
if (fileEx == "jpg " || fileEx == "bmp " || fileEx == "gif ")
{
FileUpload1.PostedFile.SaveAs(serverpath);
Response.Write( "成功 ");
Image1.ImageUrl = @ "..\aa\upload\ " + filename;
}
else
{
Response.Write( "失败 ");
}
string sql = "insert into gc_carno(id,carno,model,carphoto) values(100, ' "+TextBox1.Text+ " ', ' "+TextBox2.Text+ " ', ' "+dbpath+ " ') ";
OracleConnection conn = sda.getoracleconnection();
conn.Open();
OracleCommand cmd = new OracleCommand(sql,conn);
int i = cmd.ExecuteNonQuery();
if (i == 1)
{
Response.Write( " <script language= 'javascript '> alert( '添加成功 ') </script> ");
}
else
{
Response.Write( " <script language= 'javascript '> alert( '添加失败 ') </script> ");
}
在数据库存储的是服务器图片的物理地址，数据类型是varchar型。

㈨ e251c上传照片

㈩ 我在报名2级c语言，照片上传时显示javascript:_doPostBack("btnUpload")，是什么问题，怎么改
是javascript提交表单的机制，__doPostBack(eventTarget,eventArgument),eventTarget点击的对象比如button，eventArgument是事件的参数，button的onclick事件转化成HTML语言就是对应的__doPostBack(button的Name,''),javascript:__doPostBack('anp1','2')，anp1可能是换页的，如果是页面的话，就是anp1为页面控件，2为页码索引为第三页，找后台的anp1控件的SelectIndex_change后台事件
