我试图将此代码输出以供显示,但它给了我这个错误。有人能帮忙吗? 只要我知道哪里出错了,提示和建议就足够了。
public ObservableCollection<PData> Data = new ObservableCollection<PData>()
{
new PData() { title = "slice #1", value = 30 },
new PData() { title = "slice #2", value = 60 },
new PData() { title = "slice #3", value = 40 },
new PData() { title = "slice #4", value = 10 },
};
private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
{
pie1.DataSource = Data;
}
public class PData
{
public string title { get; set; }
public double value { get; set; }
}

此错误通常意味着您的代码中某处包含错误数量的括号{
或}
,或者您的代码不在某个类中(部分?)。
在您的情况下(如果确实是您的所有代码),以下内容:
public ObservableCollection<PData> Data (...)
不在class { ... }
范围内。
如果您的代码多于显示的代码,并且 在一个类中,请查找具有太多近括号}
的类或方法定义,这可以解释为“ 课程的结尾“。
简单的例子:
class Stuff{
public void DoStuff(){
...
}
} // accidental extra bracket ends the class Stuff too early
// Error will show here, since this appears to be outside the class:
public void DoSomethingElse(){
}
} // The inteded end of Stuff to be

public class NameList : ObservableCollection<PersonName>
{
public NameList() : base()
{
Add(new PersonName("Willa", "Cather"));
Add(new PersonName("Isak", "Dinesen"));
Add(new PersonName("Victor", "Hugo"));
Add(new PersonName("Jules", "Verne"));
}
}
public class PersonName
{
private string firstName;
private string lastName;
public PersonName(string first, string last)
