使用步骤:

1.创建验证类

2.界面调用验证类中的方法进行验证

实例代码演示如下

1.创建验证类

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Text.RegularExpressions;namespace Mobot.TeamFoundation.Client.UI.Users{    public class Validator    {        /// 
        /// 验证手机号码        /// 
        ///         /// 
             public static bool IsMobilePhone(string source)        {            return Regex.IsMatch(source, @"^1[358]\d{9}$", RegexOptions.IgnoreCase);        }        /// 
        /// 验证邮箱        /// 
        ///         /// 
             public static bool IsEmail(string source)        {            return Regex.IsMatch(source, @"^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@" +            @"([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$", RegexOptions.IgnoreCase);        }    }}

2.界面调用验证类中的方法进行验证

private void btnAdd_Click(object sender, EventArgs e)        {            if (string.IsNullOrEmpty(txtUserName.Text)||this.txtUserName.Text.Trim().Length>50)            {                XtraMessageBox.Show("用户名不能为空，且字符不能超过50个！", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);                txtUserName.Focus();                txtUserName.SelectAll();                return;            }            if (string.IsNullOrEmpty(txtDisplayName.Text) || this.txtDisplayName.Text.Trim().Length > 50)            {                XtraMessageBox.Show("显示名不能为空，且字符不能超过50个！", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);                txtDisplayName.Focus();                txtDisplayName.SelectAll();                return;            }            if (!Validator.IsMobilePhone(txtPhoneNumber.Text.Trim()))            {                XtraMessageBox.Show("请检查手机号是否输入有误！", "提示信息", MessageBoxButtons.OK, MessageBoxIcon.Information);                cbbRoleId.Focus();                this.txtPhoneNumber.Focus();                this.txtPhoneNumber.SelectAll();                return;            }            if (!Validator.IsEmail(this.txtEmail.Text.Trim()))            {                MessageBox.Show("邮箱地址格式不正确！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                this.txtEmail.Focus();                this.txtEmail.SelectAll(); ;                return;            }            if (this.cbbRoleId.SelectedIndex == -1)            {                MessageBox.Show("请选择角色！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                this.cbbRoleId.Focus();                return;            }        }

 杂记:下面是本人的邮箱另一种简单验证,可行性还求高人指点,是否可行?

if (!this.txtEmail.Text.Trim().Contains("@"))            {                MessageBox.Show("邮箱地址格式不正确！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                this.txtEmail.Focus();                this.txtEmail.SelectAll(); ;                return;            }            if (this.txtEmail.Text.Trim().Length == 0 || this.txtEmail.Text.Trim().Length > 50)            {                MessageBox.Show("邮箱不能为空，且字符不能超过50个！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                this.txtEmail.Focus();                this.txtEmail.SelectAll(); ;                return;            }            if (!Validator.IsEmail(this.txtEmail.Text.Trim()))            {                MessageBox.Show("邮箱地址格式不正确！", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);                this.txtEmail.Focus();                this.txtEmail.SelectAll(); ;                return;            }

 补充:验证服务端IP @2013.01.29

/// 
        /// 验证服务端IP        /// 
        /// 
             public static bool ValidateIpAddress(string ip, out string msg)        {            msg = string.Empty;            string strReg = @"^(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9])\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[1-9]|0)\.(25[0-5]|2[0-4][0-9]|[0-1]{1}[0-9]{2}|[1-9]{1}[0-9]{1}|[0-9])$";            System.Text.RegularExpressions.Regex regex = new System.Text.RegularExpressions.Regex(strReg);            if (!regex.IsMatch(ip))            {                msg = "配置的IP地址格式不正确!";                return false;            }            return true;        }
