TextCopy .NET Library

The static ClipboardService is not supported in Blazor because it requires JSInterop. Instead, you must inject IClipboard into your components.

Note: Blazor support requires the browser APIs clipboard.readText and clipboard.writeText to be available.

// In Program.cs
var builder = WebAssemblyHostBuilder.CreateDefault();
var serviceCollection = builder.Services;
serviceCollection.InjectClipboard();
builder.RootComponents.Add<App>("app");

// In a Blazor Component
public partial class IndexModel : ComponentBase
{
    [Inject]
    public IClipboard Clipboard { get; set; }

    public string Content { get; set; }

    public Task CopyTextToClipboard() =>
        Clipboard.SetTextAsync(Content);

    public async Task ReadTextFromClipboard() =>
        Content = await Clipboard.GetTextAsync();
}

You can register the clipboard service in your IServiceCollection to use the instance-based API via dependency injection. Use IClipboard to consume the service. For testing purposes, you can also use InjectMockClipboard to inject a MockClipboard with stubbed methods.

// Registering the service
serviceCollection.InjectClipboard();

// For testing (injects MockClipboard)
serviceCollection.InjectMockClipboard();

TextCopy is a cross-platform package for copying text to and from the clipboard. You can install it via the NuGet package manager.

For simple use cases, you can use the static ClipboardService class to interact with the clipboard without managing instances.

// Copy text to clipboard
await ClipboardService.SetTextAsync("Text to place in clipboard");
ClipboardService.SetText("Text to place in clipboard");

// Get text from clipboard
var text = await ClipboardService.GetTextAsync();
var text = ClipboardService.GetText();

// Clear the clipboard
ClipboardService.SetText("");
await ClipboardService.SetTextAsync("");

In addition to the static API, you can use the Clipboard class directly by creating an instance.

Clipboard clipboard = new();
clipboard.SetText("Text to place in clipboard");

TextCopy is cross-platform and supports:

• Windows: .NET Framework 4.6.1+, .NET Core 2.0+, Mono 5.0+
• OSX: .NET Core 2.0+, Mono 5.20.1+
• Linux: .NET Core 2.0+, Mono 5.20.1+
• Mobile: Xamarin.Android 9.0+, Xamarin.iOS 10.0+
• Web: Blazor WebAssembly 6.0+

Linux Requirement: Linux users must have xsel installed and available in the system path to access the clipboard.
