A Vector is a dense array. Unlike an Array, which may have values in indices 0 and 7 even if there are no values in positions 1 through 6, a Vector must have a value (or null) in each index. A Vector can optionally be fixed-length, meaning the number of elements it contains can'...
declare an array by specifying the type of its elements. If you want the array to store elements of any type, you can specifyobjectas its type. In the unified type system of C#, all types, predefined and user-defined, reference types and value types, inherit directly or indirectly ...

使用Array 类可以访问和操作数组。Array 索引从零开始,这意味着数组中的第一个元素为[0],第二个元素为[1],依此类推。要创建 Array 对象,可以使用new Array()构造函数。Array()还可以作为函数调用。此外,还可以使用数组访问 ([]) 运算符初始化数组或访问数组元素。
Reference-type elements are initialized to null. Value-type elements are initialized to zero. This method is an O(n) operation, where n is the product of all values in lengths. Applies to .NET 10 and other versions ProductVersions .NET Core 1.0, Core 1.1, Core 2.0, Core 2.1, Core 2....
