我想验证文本框中的输入，使其为整数，范围为0-255。我有一个小的asp.net mvc4项目

Answer 1

使用数据注释：http://www.asp.net/mvc/tutorials/mvc-music-store/mvc-music-store-part-6

[Required(ErrorMessage = "Value must be set")]
[Range(0, 250, ErrorMessage = "Value must be between 0 and 250")]
public int Value{ get; set; }

Answer 2

对于任何整数，请使用以下方法：

[Required(ErrorMessage = "Value must be set")]
[Range(0, int.MaxValue, ErrorMessage = "Value must be between 0 and 250")]
public int Value{ get; set; `enter code here`}
