我通过CodeSmith生成数据实体类，并为一些验证例程使用属性。下面是一个示例：

/// <summary>
/// Firm ID
/// </summary>
[ChineseDescription("送样单位编号")]
[ValidRequired()]
public string FirmGUID
{
    get { return _firmGUID; }
    set { _firmGUID = value; }
}

我得到了一个实用程序类，根据附加到数据实体类的属性进行验证。代码如下：

namespace Reform.Water.Business.Common
{
/// <summary>
/// Validation Utility
/// </summary>
public static class ValidationUtility
{
    /// <summary>
    /// Data entity validation
    /// </summary>
    /// <param name="data">Data entity object</param>
    /// <returns>return true if the object is valid, otherwise return false</returns>
    public static bool Validate(object data)
    {
        bool result = true;
        PropertyInfo[] properties = data.GetType().GetProperties();
        foreach (PropertyInfo p in properties)
        {
            //Length validatioin
            Attribute attribute = Attribute.GetCustomAttribute(p,typeof(ValidLengthAttribute), false);
            if (attribute != null)
            {
                ValidLengthAttribute validLengthAttribute = attribute as ValidLengthAttribute;
                if (validLengthAttribute != null)
                {
                    int maxLength = validLengthAttribute.MaxLength;
                    int minLength = validLengthAttribute.MinLength;
                    string stringValue = p.GetValue(data, null).ToString();
                    if (stringValue.Length < minLength || stringValue.Length > maxLength)
                    {
                        return false;
                    }
                }
            }
            //Range validation
            attribute = Attribute.GetCustomAttribute(p,typeof(ValidRangeAttribute), false);
            if (attribute != null)
            {
                ValidRangeAttribute validRangeAttribute = attribute as ValidRangeAttribute;
                if (validRangeAttribute != null)
                {
                    decimal maxValue = decimal.MaxValue;
                    decimal minValue = decimal.MinValue;
                    decimal.TryParse(validRangeAttribute.MaxValueString, out maxValue);
                    decimal.TryParse(validRangeAttribute.MinValueString, out minValue);
                    decimal decimalValue = 0;
                    decimal.TryParse(p.GetValue(data, null).ToString(), out decimalValue);
                    if (decimalValue < minValue || decimalValue > maxValue)
                    {
                        return false;
                    }
                }
            }
            //Regex validation
            attribute = Attribute.GetCustomAttribute(p,typeof(ValidRegExAttribute), false);
            if (attribute != null)
            {
                ValidRegExAttribute validRegExAttribute = attribute as ValidRegExAttribute;
                if (validRegExAttribute != null)
                {
                    string objectStringValue = p.GetValue(data, null).ToString();
                    string regExString = validRegExAttribute.RegExString;
                    Regex regEx = new Regex(regExString);
                    if (regEx.Match(objectStringValue) == null)
                    {
                        return false;
                    }
                }
            }
            //Required field validation
            attribute = Attribute.GetCustomAttribute(p,typeof(ValidRequiredAttribute), false);
            if (attribute != null)
            {
                ValidRequiredAttribute validRequiredAttribute = attribute as ValidRequiredAttribute;
                if (validRequiredAttribute != null)
                {
                    object requiredPropertyValue = p.GetValue(data, null);
                    if (requiredPropertyValue == null || string.IsNullOrEmpty(requiredPropertyValue.ToString()))
                    {
                        return false;
                    }
                }
            }
        }
        return result;
    }
}
}

// on configuration sections
[ConfigurationProperty] 

// in asp.net
[NotifyParentProperty(true)]

在霍夫斯塔德精神中，[Attribute]属性非常有用，因为它是您创建自己属性的方式。我使用了属性而不是接口来实现插件系统，为Enum添加描述，模拟多重调度和其他技巧。

如果我要进行代码覆盖率爬网，我认为这两个将是最好的：

 [Serializable]
 [WebMethod]

我喜欢System.Diagnostics中的[DuggerStepThrough]。

它非常方便，可以避免使用那些单行do-nothing方法或财产（如果您被迫在早期的.Net中工作，而没有自动财产）。将属性放在一个短方法或属性的getter或setter上，即使在调试器中单击“stepinto”，您也会立即执行。

[TypeConverter(typeof(ExpandableObjectConverter))]

告诉设计器展开财产，这些属性是（控件的）类

[Obfuscation]

指示混淆工具对程序集、类型或成员执行指定的操作。（尽管通常使用程序集级别[Assembly:ObfuscateAssemblyAttribute（true）]
