Question

我已经编写了以下代码，当它只是将文件上传到文件夹时，一切都很好。我已将其更改为将文件名和文件路径插入数据库，但我收到错误消息：

名称为＆＃39; DataUpload＆＃39;的字段或媒体资源未在所选数据源中找到

DataUpload是文件夹名称，之前工作正常。我可能遗漏了一些简单的东西，但我没有看到它。

protected void ButtonSubmit_Click(object sender, EventArgs e)
{

    try
    {

        FileUpload1.SaveAs(Server.MapPath("DataUpload\\" + FileUpload1.FileName));
        Guid newGUID = Guid.NewGuid();

        SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);
        conn.Open();

        string FileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
        string InsertUser = "INSERT INTO UserUpload (ID, Comment, FilePath, FileName) VALUES (@ID, @Comment, @FilePath, @FileName)";

        SqlCommand com = new SqlCommand(InsertUser, conn);

        com.Parameters.AddWithValue("@ID", newGUID.ToString());
        com.Parameters.AddWithValue("@Comment", TextBoxComment.Text);
        com.Parameters.AddWithValue("@FilePath", "DataUpload/" + FileName);
        com.Parameters.AddWithValue("@FileName", FileName);

        com.ExecuteNonQuery();
        LabelMessage.Text = ("Your Upload Is Complete");


        conn.Close();


    }
    catch (Exception ex)
    {

        LabelMessage.Text = ("Error:" + ex.Message);

    }
}

为您为FilePath创建的字符串添加单引号，例如：string.Format("'DataUpload/{0}'", FileName);

文件上传错误，“未在选定的数据源上找到”
