范围DataAnnotation似乎不适用于.Net 3.5

Question

使用.Net 3.5

我在属性上有一个范围属性（System.ComponentModel.DataAnnotations）...

   [Range(0, 5, ErrorMessage = "Weight must be between 0 and 5")]
    public virtual double Weight{ get; set; }

我在类中有一个验证验证属性的验证方法......

protected virtual void Validate()
{
    var type = this.GetType();
    foreach (var property in type.GetProperties())
    {
        foreach (ValidationAttribute attribute in 
            property.GetCustomAttributes(typeof(ValidationAttribute),true))
        {
            if(!attribute.IsValid(property.GetValue(this, null)))
            {
                BrokenRules.Add(attribute.ErrorMessage);
            }
        }
    }
}

    public virtual bool IsValid()
    {
        return GetBrokenRules().Count == 0;
    }

我有一个测试验证的NUnit测试......

[TestCase(-.1, Result = false)] // fails
[TestCase(0.0, Result = true)]
[TestCase(5.0, Result = true)]
[TestCase(5.1, Result = false)]  // fails
public bool ItValidatesWeight(double weight)
{
    _ornament.Weight = weight;
    return _ornament.IsValid();
}

必需属性正常工作但在类上正确测试，但Range属性不正常。有什么建议吗？

它将属性解释为使用int重载。

它适用于：

[Range(0.0, 5.0, ErrorMessage = "Weight must be between 0 and 5")]
    public virtual double Weight{ get; set; }
