按钮没有正确的签名 xamarin [英] Button does not have the correct signature xamarin

问题描述

我正在处理一个 Xamarin.Forms 项目，但我遇到了这个错误，我几个小时都无法解决.我希望有人以前遇到过类似的问题并可以分享他们的经验.

I'm working on a Xamarin.Forms project and I've had this error I cant solve for hours now. I'm hoping that someone has experienced a similar problem previously and can share their experience.

我得到 一个 Xamarin.Forms.Xaml.XamlParseException 被抛出

和这个消息 位置 23:5.方法 EditInfoClicked 没有正确的签名

我的代码看起来像这样.

My code looks like this.

XAML 语法:

    <StackLayout x:Name="_MapStack">
    <Button BackgroundColor="#40A6FF" 
            WidthRequest="100"
            BorderRadius="3" 
            Text="Edit" 
            FontSize="16" 
            TextColor="White"
            Clicked="EditInfoClicked" />

和 C# 语法

    async Task EditInfoClicked(object sender, EventArgs e)
    {
        ProfileDetailViewModel viewModel = new 
        ProfileDetailViewModel (Navigation, user);
        var profileDetailPage = new shared.MyProfilePage()

        {
            BindingContext = viewModel
        };

        await Navigation.PushAsync(profileDetailPage);
    }

推荐答案

您不能将事件的任务更改为 -> 事件必须使用 async void

You cant have Task for events change to -> events will have to use async void

async void EditInfoClicked(object sender, EventArgs e)
    {
        ProfileDetailViewModel viewModel = new 
        ProfileDetailViewModel (Navigation, user);
        var profileDetailPage = new shared.MyProfilePage()

        {
            BindingContext = viewModel
        };

        await Navigation.PushAsync(profileDetailPage);
    }
