在 Xamarin.Essentials, there is a Share class 中使应用程序能够与设备上的其他应用程序共享文本和 Web 链接等数据。

例如：

using Xamarin.Essentials;

public class ShareTest
{
    public async Task ShareText(string text)
    {
        await Share.RequestAsync(new ShareTextRequest
            {
                Text = text,
                Title = "Share Text"
            });
    }

    public async Task ShareUri(string uri)
    {
        await Share.RequestAsync(new ShareTextRequest
            {
                Uri = uri,
                Title = "Share Web Link"
            });
    }
}

    Thank you for your contributions but here is my code for your kind help.
    Please put me true because I'm new in Xamarin.Forms.
       
    This is my TextPage.xaml:
    
    <?xml version="1.0" encoding="utf-8" ?>
    <ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
                 xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
                 xmlns:d="http://xamarin.com/schemas/2014/forms/design"
                 xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
                 mc:Ignorable="d"
                 x:Class="Manytext.File.TextPage"
                 Title="Title">
    
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto" />
                <RowDefinition Height="*" />
            </Grid.RowDefinitions>
            <StackLayout Orientation="Horizontal" HorizontalOptions="Center" VerticalOptions="Center">
                <ContentView>
                    <Label Text="Subheading"
                           HorizontalOptions="CenterAndExpand"
                           VerticalOptions="Center" />
                </ContentView>
            </StackLayout>
            <ScrollView Grid.Row="1">
                <StackLayout Orientation="Vertical" Padding="16,10,16,10" Spacing="10">
                    <Label Text="Many text is here">
                    <Label Text="Many text is here">
                    <Label Text="Many text is here">
                    <Label Text="Many text is here">
    
                    <Button x:Name="ButtonShare"
                            Clicked="ShareText_OnClicked"
                            HorizontalOptions="Center"
                            VerticalOptions="CenterAndExpand"
                            Text="Share" />
                </StackLayout>
            </ScrollView>
        </Grid>
    
    </ContentPage>
    
    This is my TextPage.xaml.cs:
    
using System;
using Xamarin.Forms;
using Xamarin.Forms.Xaml;
using Xamarin.Essentials;

namespace Manytext.File
{
    public partial class TextPage : ContentPage
    {
        public TextPage()
        {
            InitializeComponent();
        }
        private async void ShareText_OnClicked(object sender, EventArgs e)
        {
            await Share.RequestAsync(new ShareTextRequest
            {
                Title = "Share!"
            });
        }
    }
}
