C# 上传大量数据时页面卡死

[kekemans]

向数据库发送文件 数据过大时界面就会卡死 等操作完服务器库才会返回结果 如何解决卡死的问题啊 各路大神求解救

用多线程啊,不要把耗时的操作都放主线程里

楼上兄弟说的正解

//上传数据实现 public bool UpLoading() { System.Threading.Thread.Sleep(100); string filename; int node_count = 0; filename = "/"; //遍历树型控件 if (GuanTreeView.Nodes[0] == null) { return false; } if (GuanTreeView.Nodes[0].Nodes[0] == null) { return false; } FileStream fs; string curr_path = System.Environment.CurrentDirectory; DateTime curr_date_time = new System.DateTime(); curr_date_time = System.DateTime.Now; int i = 0; node_count = GuanTreeView.Nodes[0].GetNodeCount(true); for (i = 0; i < node_count; i++) { if (GuanTreeView.Nodes[0].Nodes[i].Checked == true) { //组成文件名 string sel_string = this.GuanTreeView.Nodes[0].Nodes[i].Text.ToString(); string tmp1 = sel_string.Substring(0, sel_string.IndexOf('-')); int i_start = Convert.ToInt32(tmp1); int j = i_start / 1000; file_name = curr_path + "\\tmp\\" + txtBranCode.Text + curr_date_time.Year.ToString() + curr_date_time.Month.ToString() + curr_date_time.Day.ToString() + j.ToString() + ".txt"; //先发送一个指令过去 string zhiling = "9999|" + txtBranCode.Text + curr_date_time.Year.ToString() + curr_date_time.Month.ToString() + curr_date_time.Day.ToString() + j.ToString() + ".txt|1|"; //接收到返回指令后开始传文件 byte[] buffer = new byte[2048]; buffer = Encoding.Default.GetBytes(zhiling); LoginForm.m_socket.Send(buffer); System.Threading.Thread.Sleep(10); fs = File.Open(file_name, FileMode.Open); StreamReader sr = new StreamReader(fs); zhiling = "9999|" + txtBranCode.Text + curr_date_time.Year.ToString() + curr_date_time.Month.ToString() + curr_date_time.Day.ToString() + j.ToString() + ".txt|2|"; buffer = Encoding.Default.GetBytes(zhiling); LoginForm.m_socket.Send(buffer); System.Threading.Thread.Sleep(100); } } return true; } 这是上传的方法 怎么多线程不能卡死

多线程操作，就不会影响主线程，比较简单的方法，定义一个TaskFactory taskFactory=new TaskFactory(); taskFactory.StartNew(()=>{里面是要放入多线程执行的代码 }); 比用Thread这个创建多线程简单，不懂上网查查就知道了

那执行完了怎么返回说执行完了？
