覆盖 MVC 中的最大长度错误消息
Override max length error message in MVC
我正在尝试覆盖 ASP.net MVC 中的最大长度错误消息。基本上,我想使错误消息字符串如下:
[DisplayName] 长度不应超过 [x]。但是,我不知道如何在里面包含displayname属性值。
public class MyMaxLengthAttribute : MaxLengthAttribute
{
public MyMaxLengthAttribute(int length) : base(length)
{
ErrorMessage = "What should I input here"
}
}
如果使用StringLengthAttribute
{0}
指的是显示名称,{2}
指的是长度。
public class MyMaxLengthAttribute : StringLengthAttribute
{
public MyMaxLengthAttribute(int length) : base(length)
{
ErrorMessage = "{0} length should not be more than {2}"
}
}
嗨,我这里没有电脑,但我相信你必须按照以下方式做一些事情。
public class MyMaxLengthAttribute : MaxLengthAttribute
{
private static String CustomErrorMessage = "{0} length should not be more than {1}";
public MyMaxLengthAttribute(int length) : base(length)
{
ErrorMessage = "What should I input here"
}
public override string FormatErrorMessage(string name)
{
if (!String.IsNullOrEmpty(ErrorMessage))
{
ErrorMessage = MyErrorMessage;
}
return String.Format(CultureInfo.CurrentUICulture, CustomErrorMessage , name);
}
}
