我显然可以自己解析,但它是一个黑客,我希望路径支持comboBox.SelectedValuePath的一切(为了一致性).

结果(感谢Aran Mulholland)：

不知道这一点的表现,但是我现在并不在意.

public class BindingEvaluator {
    #region Target Class

    private class Target : DependencyObject {
        public static readonly DependencyProperty ResultProperty = DependencyProperty.Register(
            "Result",typeof(IEnumerable),typeof(BindingEvaluator)
        );

        public object Result {
            get { return this.GetValue(ResultProperty); }
            set { this.SetValue(ResultProperty,value); }
        }
    }

    #endregion

    public object GetValue(object source,string propertyPath) {
        var target = new Target();
        BindingOperations.SetBinding(target,Target.ResultProperty,new Binding(propertyPath) {
            Source = source,Mode = BindingMode.OneTime
        });
        return target.Result;
    }
}
