使用Microsoft Visual Studio 2005怎么实现上传图片

使用Microsoft Visual Studio 2005怎么实现上传图片
恩 上穿图片后 图片保存到某个文件夹中 并储存该图片保存后的路径
在我的代码中修改
protected void btnAdd_Click(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["aspnetdbConnectionString"].ConnectionString))
{
con.Open();
using (SqlCommand cmd = new SqlCommand("putinfo", con))
{
cmd.CommandType = CommandType.StoredProcedure;
SqlParameter p1 = new SqlParameter();
p1.ParameterName = "@title";
p1.SqlValue = txtTitle.Text.Trim();
cmd.Parameters.Add(p1);
SqlParameter p2 = new SqlParameter();
p2.ParameterName = "@lei";
p2.SqlValue = DropDownList1.SelectedValue.Trim();
cmd.Parameters.Add(p2);
SqlParameter p3 = new SqlParameter();
p3.ParameterName = "@content";
p3.SqlValue = txtContent.Text.Trim();
cmd.Parameters.Add(p3);
SqlParameter p4 = new SqlParameter();
p4.ParameterName = "@picture";
p4.SqlValue = fupPicture.PostedFile.FileName;
fupPicture.SaveAs(Server.MapPath(pictureFileName));
cmd.Parameters.Add(p4);
cmd.Prepare();
int fetchnum = cmd.ExecuteNonQuery();
if (fetchnum >= 1)
{
Response.Write("<script language=javascript>alent('发布新消息成功!');</script>");

}
else
{
Response.Write("<script language=javascript>alent('发布新消息失败!');</script>");
}

}
}
}
多了一句 fupPicture.SaveAs(Server.MapPath(pictureFileName));这个

protected void btnAdd_Click(object sender, EventArgs e)
{
using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["aspnetdbConnectionString"].ConnectionString))
{
con.Open();
using (SqlCommand cmd = new SqlCommand("putinfo", con))
{

string imgPath=""//图片上传路径，如 upload/xxx.jpg
try{
fupPicture.SaveAs(Server.MapPath(imgPath)); //图片上传的代码
}
catch{//上传失败的程序处理}

cmd.CommandType = CommandType.StoredProcedure;
SqlParameter p1 = new SqlParameter();
p1.ParameterName = "@title";
p1.SqlValue = txtTitle.Text.Trim();
cmd.Parameters.Add(p1);
SqlParameter p2 = new SqlParameter();
p2.ParameterName = "@lei";
p2.SqlValue = DropDownList1.SelectedValue.Trim();
cmd.Parameters.Add(p2);
SqlParameter p3 = new SqlParameter();
p3.ParameterName = "@content";
p3.SqlValue = txtContent.Text.Trim();
cmd.Parameters.Add(p3);
SqlParameter p4 = new SqlParameter();
p4.ParameterName = "@picture";
//p4.SqlValue = fupPicture.PostedFile.FileName;
p4.SqlValue = imgPath;//保存了路径
cmd.Parameters.Add(p4);
cmd.Prepare();
int fetchnum = cmd.ExecuteNonQuery();
if (fetchnum >= 1)
{
Response.Write("<script language=javascript>alent('发布新消息成功!');</script>");

}
else
{
Response.Write("<script language=javascript>alent('发布新消息失败!');</script>");
}

}
}
}
