在这里,我写的上传图片的编码control.but获得在SqlConnection的地方一些运行时error.error母猪 首先我
1.图像名称框 - 文本框
2.Image上传控制 - ASP imageupload控件
3.上传按钮
的SqlConnection运行时错误
错误:从未同步的代码块调用对象同步方法。
代码下面
public partial class ProfileDetails : System.Web.UI.Page
{
string connStr = ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
//SqlConnection con = new SqlConnection("Data Source=CHATHU-LAPTOP;Initial Catalog=ProfilemgtDB;User ID=sa;Password=sa123");
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
}
protected void Upload_Click(object sender, EventArgs e)
{
string path = Server.MapPath("images/");
if (FileUpload1.HasFile)
{
string ext = Path.GetExtension(FileUpload1.FileName);
if (ext == ".jpg" || ext == ".png")
{
FileUpload1.SaveAs(path + FileUpload1.FileName);
string name = "~/images/" + FileUpload1.FileName;
string s = "Insert into Profile values('" + TextBox12.Text.Trim() + " '.'" + name + "')";
SqlConnection con = new SqlConnection(connStr);
SqlCommand cmd = new SqlCommand(s, con);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
Response.Write("File Uploaded");
}
else
{
Response.Write("You can upload only JPG & PNG");
}
}
else {
Response.Write("Please Select File");
}
}
}
ERROR:对象同步方法是从代码不同步块调用。
哪一行是抛出该错误? –
SqlConnection con = new SqlConnection(connStr); –
可能与你的错误没有任何关系,但是这个代码是一个等待发生的灾难。切勿使用字符串连接来创建sql值以传递INSERT,UPDATE,DELETE,SELECT等操作 – Steve
