Xna错误 - spriteFont

Question

我的spriteFont文件出现了一个奇怪的错误。只要我添加一个字体，我就会得到4个错误;

“命名空间不直接包含字段或方法等成员”（“<?xml version="1.0" encoding="utf-8"?>”）第1行，

“预处理程序指令必须显示为行上的第一个非空白字符”（“<Start>&#32;</Start>”）第55行，

“预处理程序指令必须显示为行上的第一个非空白字符”（“<End>&#126;</End>”）第56行，并且

“字符”，十六进制值0x1a在XML文档中是非法的。“ （“<End>&#126;</End>”）第56行

xml文件中的代码是

<?xml version="1.0" encoding="utf-8"?>
