C# 获取名为'；XamlParseException'；

我在尝试开发应用程序时遇到此错误，编译器说找不到错误代码。所以我没有更多的信息。我知道错误是在尝试初始化组件时产生的。 以下是我的页面代码：

经过长时间的尝试和错误，我找到了问题所在。在最深的网格中，错误是在尝试创建TextBox时生成的，不知道为什么，因为如果您只是删除TextBox，它会正常工作。 这里是错误

谢谢你的帮助。

请注意这两行：

<TextBox  Grid.Row="1" Grid.Column=" 0" x:Name="nifBox" PlaceholderText="DNI..." FontSize="20" Background="Gray"  VerticalAlignment="Center" Margin="29,0,30,0"  />
<TextBox x:Name="nameBox" Grid.Row="3" Grid.Column=" 0" PlaceholderText="Nombre..." FontSize="20" Background="Gray"  VerticalAlignment="Center" Margin="30,0,30,0"  />

在Grid.Column中，0值之前有一个额外的空格。您需要通过“0”而不是“0”
