调用通用验证类
通过数据验证
如果SQL有了身份证信息新增的身份证号不能是重复的
编写查询身份证方法
/// <summary>
/// 查询身份证是否已经存在
/// </summary>
/// <param name="idcard"></param>
/// <returns></returns>
public bool IsIdCardExisted(string idcard)
{
string sql = "Select count(*) from Students where StudentIdNo={0}";
sql = string.Format(sql, idcard);
int count = Convert.ToInt32(SQLHelper.GetSingleResult(sql));
if (count == 1) return true;
else return false;
}
通过数据验证
SQL已经有了存在的身份证号,新增的身份证号重复不通过
//验证身份证号是否和出生日期吻合
string month = string.Empty;
string day = string.Empty;
if(Convert.ToDateTime(this.txtBirthday.Text).Month<10)
month = "0" + Convert.ToDateTime(this.txtBirthday.Text).Month.ToString();
else
month = Convert.ToDateTime(this.txtBirthday.Text).Month.ToString();
if (Convert.ToDateTime(this.txtBirthday.Text).Day < 10)
day = "0" + Convert.ToDateTime(this.txtBirthday.Text).Day.ToString();
else
day = Convert.ToDateTime(this.txtBirthday.Text).Day.ToString();
string birthday = Convert.ToDateTime(this.txtBirthday.Text).Year.ToString() + month + day;
if(!this.txtStuIdNo.Text.Trim().Contains(birthday))
{
MessageBox.Show("身份证号和出生日期不匹配", "验证提示");
this.txtStuIdNo.Focus();
this.txtStuIdNo.SelectAll();
return;
}
