从Task更新进度条.运行异步 [英] Update progress bar from Task.Run async

问题描述

我有一种从用户信息生成软件激活密钥的方法:

I have a method to generate software activation key from User Information:

private async void GenerateAsync()
        {
            await Task.Run(() =>
            {
                var secretstring = "CustomerName >> " + txtFullname.Text + " >> " + txtproducid.Text;
                keymng = new KeyManager(secretstring);
                var dateexp = numExpdate.Value;
                if (dateexp == 0)
                {
                    dateexp = 730000;
                }

                if (cbLicenseType.SelectedIndex == 0)
                {
                    kvc = new KeyValueClass()
                    {
                        LicenseType = LicenseType.FULL,
                        Header = Convert.ToByte(9),
                        Footer = Convert.ToByte(6),
                        ProductCode = PRODUCTCODE,
                        Edition = (Edition)Enum.Parse(typeof(Edition), cbEdition.SelectedText),
                        Version = 1,
                        Expiration = DateTime.Now.AddDays(Convert.ToInt32(dateexp))
                    };

                    if (!keymng.GenerateKey(kvc, ref productkey))
                    {
                        //Handling Error
                    }
                }
                else
                {
                    kvc = new KeyValueClass()
                    {
                        LicenseType = LicenseType.TRIAL,
                        Header = Convert.ToByte(9),
                        Footer = Convert.ToByte(6),
                        ProductCode = PRODUCTCODE,
                        Edition = (Edition)Enum.Parse(typeof(Edition), cbEdition.SelectedText),
                        Version = 1,
                        Expiration = DateTime.Now.AddDays(Convert.ToInt32(dateexp))
                    };
                    if (!keymng.GenerateKey(kvc, ref productkey))
                    {
                        //Handling Error
                    }
                }
            });

        }

，我有进度栏.我想异步运行此方法，并将进度更新到progressbar.如何使用async-await方法更新UI. BackgroundWorker是替代品?

and I have progressbar. I want to run this method async and update progress to progressbar. How to update UI with async-await method. BackgroundWorker is alternative???

推荐答案

我在Winforms中使用此方法:

I use this method in Winforms:

progressBar1.Invoke((Action)(() => progressBar1.Value=50))
