[DeploymentItem（“myFile1.txt”）]DeploymentItem上的MSDN文档

如果您正在对文件进行测试或将该文件用作测试的输入，那么这非常有用。

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]

我认为这里必须提到以下属性也非常重要：

STAThreadAttribute 

指示应用程序的COM线程模型是单线程单元（STA）。

例如，此属性用于Windows窗体应用程序：

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

而且。。。

SuppressMessageAttribute

禁止报告特定的静态分析工具规则冲突，允许对单个代码工件进行多次禁止。

例如：

[SuppressMessage("Microsoft.Performance", "CA1801:ReviewUnusedParameters", MessageId = "isChecked")]
[SuppressMessage("Microsoft.Performance", "CA1804:RemoveUnusedLocals", MessageId = "fileIdentifier")]
static void FileNode(string name, bool isChecked)
{
    string fileIdentifier = name;
    string fileName = name;
    string version = String.Empty;
}

我建议使用nUnit库中的[TestFixture]和[Test]。

代码中的单元测试为重构和编码文档提供了安全性。

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。

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;
    }
}
