如何将backgroundWorker用于2个较长的过程取决于选择 [英] How to use backgroundWorker for 2 long processes depends upon selection

问题描述

您好，先生，我是Uday

在我的C型Winform中，

我有两个长时间运行的方法 uploadUsingText()和 uploadUsingExcel()


一次选择一个过程取决于组合框的选择.选择后，我必须显示picturebox1可见为true.处理完成后，picturebox1必须可见false.

我的代码是
像这样

 如果(isFiletypeSelect())
            {
                如果(cmbSelectFileType.Text == " )
                {
                    如果(validation())
                    {
                        panel2.Visible =  true ;
                        
                         pictureBox1.Visible =  true ;
                        uploadUsingText();
                        //  panel1.Enabled = true; 

                        panel2.Visible =  false ;

                    }
                }
                如果(cmbSelectFileType.Text == " )
                {
                    如果(validation())
                    {
                        uploadUsingExcel();
                    }

                }

            } 

如何使用backgroundWorker检查方法是否完成取决于选择?
如何根据2种长方法使用backgroundWorker取决于选择?

我已经尝试了以下代码中的上述代码

私有空backgroundWorker1_DoWork(对象发送者，DoWorkEventArgs e){}

请给我解决方法.
首先，您需要声明一个表单级别的BackGroundWorker，并在您的表单构造函数中为其DoWork事件添加一个处理程序.然后，您可以简单地在DoWork事件中运行上述代码，如下所示:

 BackgroundWorker bgw = 新 BackgroundWorker();

        公共 Form1()
        {
            InitializeComponent();
            bgw.DoWork + = 新 DoWorkEventHandler(bgw_DoWork);
            button1.Click + = 新 EventHandler(button1_Click);
        }

        无效 button1_Click(对象发​​件人，EventArgs e)
        {
            bgw.RunWorkerAsync();
        }

        无效 bgw_DoWork(对象发​​送者，DoWorkEventArgs e)
        {
            如果(cmbSelectFileType.Text == " )
            {
                如果(Validation())
                {
                    panel1.Enabled =  false ;
                    pictureBox1.Visible =  true ;
                    UpLoadUsingText();
                }
            }
            其他 如果(cmbSelectFileType.Text == "  Excel")
            {
                如果(Validation())
                {
                    panel1.Enabled =  false ;
                    pictureBox1.Visible =  true ;
                    UpLoadUsingExcel();
                }
            }
        } 

希望对您有帮助

How i can use backgroundWorker for 2 long methods depends upon selection?

I have tried for above code in following

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e){}

please give me solution.

解决方案

First of all you need to declare a form level BackGroundWorker, and in your form constructor add a handler for it''s DoWork event. Then you can simply run your above code in the DoWork event, something like this:

BackgroundWorker bgw = new BackgroundWorker();

        public Form1()
        {
            InitializeComponent();
            bgw.DoWork += new DoWorkEventHandler(bgw_DoWork);
            button1.Click += new EventHandler(button1_Click);
        }

        void button1_Click(object sender, EventArgs e)
        {
            bgw.RunWorkerAsync();
        }

        void bgw_DoWork(object sender, DoWorkEventArgs e)
        {
            if(cmbSelectFileType.Text == "Text")
            {
                if (Validation())
                {
                    panel1.Enabled = false;
                    pictureBox1.Visible = true;
                    UpLoadUsingText();
                }
            }
            else if (cmbSelectFileType.Text == "Excel")
            {
                if (Validation())
                {
                    panel1.Enabled = false;
                    pictureBox1.Visible = true;
                    UpLoadUsingExcel();
                }
            }
        }

Hope this helps
