DebuggerHiddenAttribute，它允许避免单步执行不应调试的代码。

public static class CustomDebug
{
    [DebuggerHidden]
    public static void Assert(Boolean condition, Func<Exception> exceptionCreator) { ... }
}

...

// The following assert fails, and because of the attribute the exception is shown at this line
// Isn't affecting the stack trace
CustomDebug.Assert(false, () => new Exception()); 

此外，它还防止在堆栈跟踪中显示方法，这在使用只包装另一个方法的方法时非常有用：

[DebuggerHidden]
public Element GetElementAt(Vector2 position)
{
    return GetElementAt(position.X, position.Y);
}

public Element GetElementAt(Single x, Single y) { ... }

如果现在调用GetElementAt（新的Vector2（10，10）），并且包装的方法发生错误，那么调用堆栈不会显示正在调用引发错误的方法的方法。

// on configuration sections
[ConfigurationProperty] 

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

[XmlIgnore]

因为这允许您忽略（在任何xml序列化中）“父”对象，否则在保存时会导致异常。

[Serializable]始终用于将对象序列化到外部数据源（如xml）或从远程服务器序列化对象。在这里了解更多信息。

当您在调试期间将鼠标悬停在Type的实例上时，[DuggerDisplay]对于快速查看该类型的自定义输出非常有用。例子：

[DebuggerDisplay("FirstName={FirstName}, LastName={LastName}")]
class Customer
{
    public string FirstName;
    public string LastName;
}

这是它在调试器中的外观：

此外，值得一提的是，设置了CacheDuration属性的[WebMethod]属性可以避免不必要地执行web服务方法。

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;
    }
}
