用处及效果
准备工作
思路如下：
1、确定哪些控件需要进行验证，在组件中进行属性扩展
2、定义验证规则
3、根据验证规则的正则表达式进行验证和非空验证
4、触发验证结果事件
5、进行验证结果提示
开始
添加一个验证规则枚举
/// <summary>
/// 验证规则
/// </summary>
public enum VerificationModel
{
/// <summary>
/// 无
/// </summary>
[Description("无"), VerificationAttribute()]
None = ,
/// <summary>
/// 任意字母数字下划线
/// </summary>
[Description("任意字母数字下划线"), VerificationAttribute(@"^[a-zA-Z_0-1]*$", "请输入任意字母数字下划线")]
AnyChar = ,
/// <summary>
/// 任意数字
/// </summary>
[Description("任意数字"), VerificationAttribute(@"^[\-\+]?\d+(\.\d+)?$", "请输入任意数字")]
Number = ,
/// <summary>
/// 非负数
/// </summary>
[Description("非负数"), VerificationAttribute(@"^(\+)?\d+(\.\d+)?$", "请输入非负数")]
UnsignNumber = ,
/// <summary>
/// 正数
/// </summary>
[Description("正数"), VerificationAttribute(@"(\+)?([1-9][0-9]*(\.\d{1,2})?)|(0\.\d{1,2})", "请输入正数")]
PositiveNumber = ,
/// <summary>
/// 整数
/// </summary>
[Description("整数"), VerificationAttribute(@"^[\+\-]?\d+$", "请输入整数")]
Integer = ,
/// <summary>
/// 非负整数
/// </summary>
[Description("非负整数"), VerificationAttribute(@"^(\+)?\d+$", "请输入非负整数")]
UnsignIntegerNumber = ,
/// <summary>
/// 正整数
/// </summary>
[Description("正整数"), VerificationAttribute(@"^[0-9]*[1-9][0-9]*$", "请输入正整数")]
PositiveIntegerNumber = ,
/// <summary>
/// 邮箱
/// </summary>
[Description("邮箱"), VerificationAttribute(@"^(([0-9a-zA-Z]+)|([0-9a-zA-Z]+[_.0-9a-zA-Z-]*[0-9a-zA-Z]+))@([a-zA-Z0-9-]+[.])+([a-zA-Z]{2}|net|NET|com|COM|gov|GOV|mil|MIL|org|ORG|edu|EDU|int|INT)$", "请输入正确的邮箱地址")]
Email = ,
/// <summary>
/// 手机
/// </summary>
[Description("手机"), VerificationAttribute(@"^(\+?86)?1\d{10}$", "请输入正确的手机号")]
Phone = ,
/// <summary>
/// IP
/// </summary>
[Description("IP"), VerificationAttribute(@"(?=(\b|\D))(((\d{1,2})|(1\d{1,2})|(2[0-4]\d)|(25[0-5]))\.){3}((\d{1,2})|(1\d{1,2})|(2[0-4]\d)|(25[0-5]))(?=(\b|\D))", "请输入正确的IP地址")]
IP = ,
/// <summary>
/// Url
/// </summary>
[Description("Url"), VerificationAttribute(@"^[a-zA-z]+://(//w+(-//w+)*)(//.(//w+(-//w+)*))*(//?//S*)?$", "请输入正确的网址")]
URL = ,
/// <summary>
/// 身份证号
/// </summary>
[Description("身份证号"), VerificationAttribute(@"^[1-9]\d{5}(18|19|([23]\d))\d{2}((0[1-9])|(10|11|12))(([0-2][1-9])|10|20|30|31)\d{3}[0-9Xx]$", "请输入正确的身份证号")]
IDCardNo = ,
/// <summary>
/// 正则验证
/// </summary>
[Description("自定义正则表达式"), VerificationAttribute()]
Custom = ,
}
还有一个验证规则枚举的特性
public class VerificationAttribute : Attribute
{
/// <summary>
/// Initializes a new instance of the <see cref="VerificationAttribute"/> class.
/// </summary>
/// <param name="strRegex">The string regex.</param>
/// <param name="strErrorMsg">The string error MSG.</param>
public VerificationAttribute(string strRegex = "", string strErrorMsg = "")
{
Regex = strRegex;
ErrorMsg = strErrorMsg;
}
/// <summary>
/// Gets or sets the regex.
/// </summary>
/// <value>The regex.</value>
public string Regex { get; set; }
/// <summary>
/// Gets or sets the error MSG.
/// </summary>
/// <value>The error MSG.</value>
public string ErrorMsg { get; set; } }
定义事件参数
public class VerificationEventArgs : EventArgs
{
/// <summary>
/// Gets or sets the verification control.
/// </summary>
/// <value>The verification control.</value>
public Control VerificationControl { get; set; }
/// <summary>
/// Gets or sets a value indicating whether [verify success].
/// </summary>
/// <value><c>true</c> if [verify success]; otherwise, <c>false</c>.</value>
public bool IsVerifySuccess { get; set; }
/// <summary>
/// Gets or sets the verification model.
/// </summary>
/// <value>The verification model.</value>
public VerificationModel VerificationModel { get; set; }
/// <summary>
/// 是否已处理，如果为true，则不再使用默认验证提示功能
/// </summary>
/// <value><c>true</c> if this instance is processed; otherwise, <c>false</c>.</value>
public bool IsProcessed { get; set; }
/// <summary>
/// Gets or sets 正则表达式
/// </summary>
/// <value>The custom regex.</value>
public string Regex { get; set; }
/// <summary>
/// Gets or sets a value indicating whether this <see cref="VerificationEventArgs"/> is required.
/// </summary>
/// <value><c>true</c> if required; otherwise, <c>false</c>.</value>
public bool Required { get; set; } /// <summary>
/// Gets or sets the error MSG.
/// </summary>
/// <value>The error MSG.</value>
public string ErrorMsg { get; set; }
}
添加一个类VerificationComponent继承Component，实现接口 IExtenderProvider以对控件进行扩展
定义属性
/// <summary>
/// Delegate VerificationedHandle
/// </summary>
/// <param name="e">The <see cref="VerificationEventArgs"/> instance containing the event data.</param>
public delegate void VerificationedHandle(VerificationEventArgs e);
/// <summary>
/// Occurs when [verificationed].
/// </summary>
[Browsable(true), Category("自定义属性"), Description("验证事件"), Localizable(true)]
public event VerificationedHandle Verificationed; /// <summary>

/// <summary>

Dictionary<Control, bool> m_controlRequiredCache = new Dictionary<Control, bool>();
/// <summary>
/// The m control MSG cache
/// </summary>
Dictionary<Control, string> m_controlMsgCache = new Dictionary<Control, string>();
/// <summary>
/// The m control tips
/// </summary>
Dictionary<Control, Forms.FrmAnchorTips> m_controlTips = new Dictionary<Control, Forms.FrmAnchorTips>(); /// <summary>
/// The error tips back color
/// </summary>
private Color errorTipsBackColor = Color.FromArgb(, , ); /// <summary>
/// Gets or sets the color of the error tips back.
/// </summary>
/// <value>The color of the error tips back.</value>
[Browsable(true), Category("自定义属性"), Description("错误提示背景色"), Localizable(true)]
public Color ErrorTipsBackColor
{
get { return errorTipsBackColor; }
set { errorTipsBackColor = value; }
} /// <summary>

[Browsable(true), Category("自定义属性"), Description("错误提示文字颜色"), Localizable(true)]
public Color ErrorTipsForeColor
{
get { return errorTipsForeColor; }
set { errorTipsForeColor = value; }
}
哪些控件需要进行验证（属性扩展）

{
if (extendee is TextBoxBase || extendee is UCTextBoxEx || extendee is ComboBox || extendee is UCCombox)
{
return true;
}
return false;
