| 11 | Execute a shell command in async in C# while not blocking the UI thread. | ||
| 12 | |||
| 13 | ```c# | ||
| 14 | private async Task executeCopyCommand() | ||
| 15 | { | ||
| 16 | await Task.Run(() => | ||
| 17 | { | ||
| 18 | var processStartInfo = new ProcessStartInfo("cmd", "/c dir") | ||
| 19 | { | ||
| 20 | RedirectStandardOutput = true, | ||
| 21 | UseShellExecute = false, | ||
| 22 | CreateNoWindow = true | ||
| 23 | }; | ||
| 24 | |||
| 25 | var process = new Process | ||
| 26 | { | ||
| 27 | StartInfo = processStartInfo | ||
| 28 | }; | ||
| 29 | |||
| 30 | process.Start(); | ||
| 31 | process.WaitForExit(); | ||
| 32 | }); | ||
| 33 | } | ||
| 34 | ``` | ||
| 35 | |||
| 36 | Make sure that `async` is present in the function definition and `await` is used | ||
| 37 | in the method that calls `executeCopyCommand()`. | ||
| 38 | |||
| 39 | ```c# | ||
| 40 | private async void button_Click(object sender, EventArgs e) | ||
| 41 | { | ||
| 42 | await executeCopyCommand(); | ||
| 43 | } | ||
| 44 | ``` | ||
| 45 | |||
