我相信你只能让它只读。

最好的选择:

public static readonly byte[] ZeroHash = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };

.NET Framework v4.5+解决方案，改进了tdbeckett的答案:

using System.Collections.ObjectModel;

// ...

public ReadOnlyCollection<string> Titles { get; } = new ReadOnlyCollection<string>(
  new string[] { "German", "Spanish", "Corrects", "Wrongs" }
);

注意:假定集合在概念上是常量，在类级别声明它时将其设置为静态可能是有意义的。

上面的:

Initializes the property's implicit backing field once with the array. Note that { get; } - i.e., declaring only a property getter - is what makes the property itself implicitly read-only (trying to combine readonly with { get; } is actually a syntax error). Alternatively, you could just omit the { get; } and add readonly to create a field instead of a property, as in the question, but exposing public data members as properties rather than fields is a good habit to form. Creates an array-like structure (allowing indexed access) that is truly and robustly read-only (conceptually constant, once created), both with respect to: preventing modification of the collection as a whole (such as by removing or adding elements, or by assigning a new collection to the variable). preventing modification of individual elements. (Even indirect modification isn't possible - unlike with an IReadOnlyList<T> solution, where a (string[]) cast can be used to gain write access to the elements, as shown in mjepsen's helpful answer. The same vulnerability applies to the IReadOnlyCollection<T> interface, which, despite the similarity in name to class ReadOnlyCollection, does not even support indexed access, making it fundamentally unsuitable for providing array-like access.)

数组可能是一种只能在这里求值的东西 运行时。常量必须在编译时求值。尝试使用"readonly" 而不是"const"。

你可以采用一种不同的方法:定义一个常量字符串来表示你的数组，然后在你需要它的时候把字符串分割成一个数组。

const string DefaultDistances = "5,10,15,20,25,30,40,50";
public static readonly string[] distances = DefaultDistances.Split(',');

这种方法为您提供了一个可以存储在配置中并在需要时转换为数组的常量。

作为一种替代方法，要解决使用只读数组可以修改元素的问题，可以使用静态属性。(单个元素仍然可以更改，但这些更改只会在数组的本地副本上进行。)

public static string[] Titles 
{
    get
    {
        return new string[] { "German", "Spanish", "Corrects", "Wrongs"};
    }
}

当然，这不是特别有效，因为每次都会创建一个新的字符串数组。
