添加字典

Question

我有把一本字典，具有Vector2数组作为它的值类型为字典，是一类属性的问题：

Dictionary<string, Dictionary<string, Vector2[]>> foo = new Dictionary<string, Dictionary<string, Vector2[]>>(); // OK 
foo.Add("bar", new Dictionary<string, Vector2[]>()); // OK 

fooAttribute.add("bar", new Dictionary<string, Vector2[]>()); // NOT OK 

属性的宣言是：

protected Dictionary<string, Dictionary<string, Vector2[]>> fooAttribute; 

它适用于局部变量，但它失败的属性，出现以下错误：

Error CS1061: Type System.Collections.Generic.Dictionary<string,System.Collections.Generic.Dictionary<string,UnityEngine.Vector2[]>>' does not contain a definition for add' and no extension method add' of type System.Collections.Generic.Dictionary>' could be found (are you missing a using directive or an assembly reference?) (CS1061) (Assembly-CSharp)

Answer 1

您必须使用Add而不是add。 C＃区分大小写。
