推荐答案

首先，这些都是警告，而不是错误.
第二个警告1并非来自此代码.
它可能来自if comparision，可能是您在某个位置的字符串和对象之间进行的操作.

不建议使用OuterGlowBitmapEffect ，而应使用BlurEffect.请参见此处 [

First these are both warnings and not errors.
Second warning 1 is not coming from this code.
It is probably coming from an if comparision that you may be doing between a string and an object somewhere.

OuterGlowBitmapEffect is deprecated and BlurEffect should be used instead. See here[^].
