FileChooser

Namespace: PuppeteerSharp

public class FileChooser

FileChooser objects are returned via the WaitForFileChooserAsync(WaitForOptions) method. File choosers let you react to the page requesting for a file.

Inheritance: object

In browsers, only one file chooser can be opened at a time. All file choosers must be accepted or canceled. Not doing so will prevent subsequent file choosers from appearing.

Example

var waitTask = page.WaitForFileChooserAsync();
await Task.WhenAll(
    waitTask,
    page.ClickAsync("#upload-file-button")); // some button that triggers file selection

await waitTask.Result.AcceptAsync('/tmp/myfile.pdf');
