如何在XAML的Xamarin.Forms中的Visual Studio中设置十六进制BackgroundColor和整数FontSize？ [英] How to set a hex BackgroundColor and integer FontSize in Visual Studio in Xamarin.Forms in XAML?

问题描述

我的问题是我在 Visual Studio 中遇到有关 BackgroundColor 和 fontSize 按钮上的属性。

没有Visual Studio错误的所需XAML：

 < Button Text = / Grid.Row = 1 Grid.Column = 3 
 BackgroundColor =＃FFA500 TextColor = White  
 FontSize = 36 BorderRadius = 0 /> 
  

Visual Studio错误：

但是，XAML文档将十六进制颜色设置为背景颜色，所以应该没有错误吧？：

我所做的破坏了临时解决方案的操作

我清理并构建了公共类库和平台库。我还删除了iOS和Windows手机库。这些步骤导致以下错误：

对我有用的东西

我决定创建一个新的解决方案，并接受了 FontSize = 36 和 BackgroundColor =＃808080 。我以前使用的解决方案来自一个网站。

My problem is that I am facing errors in Visual Studio about the BackgroundColor and fontSize property on my buttons.

Desired XAML without Visual Studio errors:

<Button Text="/" Grid.Row="1" Grid.Column="3"
    BackgroundColor="#FFA500" TextColor="White"
    FontSize="36" BorderRadius="0" />

The Visual Studio errors:

However, the XAML documentation sets a hex color as background color so there shouldn't be an error right?:

解决方案

Short version:

I created a new solution and it accepts the FontSize="36" and BackgroundColor="#808080". The solution I previously used came from a website.

A few days later I got another error

Installing the IDE compatibility for Visual Studio 2017 version 15.8 solved this: https://releases.xamarin.com/category/visual-studio-tools-for-xamarin/

Long version:

My temporary solution

I just set my error list to build only so I can compile my code anyway.

IntelliSense seems to generate the errors, but the hex colors and font size I declared in my XAML are working.

What I did that broke my temporary solution

I cleaned and build the public class library and the platform libraries. I also deleted the iOS and Windows phone library. These steps resulted in the errors below:
