Declare a const array in C#
In C#, use readonly to declare a const array.
public static readonly string[] a = { "Car", "Motorbike", "Cab" };
In readonly, you can set the value at runtime as well unlike const.
Another alternative of achieving what we saw above −
public ReadOnlyCollection<string> a { get { return new List<string> { "Car", "Motorbike", "Cab" }.AsReadOnly();}}
.NET framework 4.5 brings an improvement to what we saw −
public ReadOnlyCollection<string> a { get; } = new ReadOnlyCollection<string>( new string[] { "Car", "Motorbike", "Cab" } );
