C# StringValues 類型

命令空間：Microsoft.Extensions.Primitives

程序集：Microsoft.Extensions.Primitives.dll

public readonly struct StringValues : IList<string>, ICollection<string>, IEnumerable<string>, IEnumerable, IReadOnlyList<string>, IReadOnlyCollection<string>, IEquatable<StringValues>, IEquatable<string>, IEquatable<string[]>

 

var httpHeaders = HttpContext.Request.Headers;

var signature = httpHeaders["signature"];

signature 就是 StringValues類型

//IList<string> 顯式實現接口

((IList<string>)signature).IndexOf
