我的类是这样写的
/// <summary>
/// 管理员登录
/// </summary>
/// <param name="AdminName">管理员名字</param>
/// <param name="AdminPwd">管理员密码</param>
/// <param name="Reint">登录状态信息</param>
/// <returns>返回信息：0：登录成功，-1：用户不存在，-2：密码不正确</returns>
public DataSet UserLogin(String AdminName, String AdminPwd,ref Int32 Reint)
{
String Pass = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(AdminPwd, "MD5");
DataSet ReDataSet;
try
{
Con.Open();
SqlStr = "SELECT * FROM Admin WHERE Admin_Name=" + AdminName;
SqlDataAdapter Sda = new SqlDataAdapter();
Sda.SelectCommand = new SqlCommand(SqlStr,Con);
ReDataSet = new DataSet();
Sda.Fill(ReDataSet,"AdminList");
if (ReDataSet.Tables[0].Rows.Count > 0)
{
if (ReDataSet.Tables[0].Rows[0]["Admin_Password"].ToString() == Pass)
{
Reint = 0;
}
else
{
Reint = -2;
}
}
else
{
Reint = -1;
}
}
catch(Exception Ex)
{
throw new Exception("出错原因：" + Ex.Message);
}
return ReDataSet;
}
然后我是这样调用的：
UserOperate UO = new UserOperate();
protected void Page_Load(object sender, EventArgs e)
{
this.Page.Title = "管理员登录~~！";
}
protected void Button1_Click(object sender, EventArgs e)
{
Int32 Int;
DataSet DS = new DataSet();
DS = UO.UserLogin(this.TextBox1.Text.Trim(),this.TextBox2.Text.Trim(), Int);
switch (Int)
{
case 0:
Response.Redirect("Default.aspx");
case -1:
this.Label1.Visible = true;
this.Label1.Text="该用户不存在！";
case -2:
this.Label1.Visible=true;
this.Label1.Text="您的密码不正确！";
}
}
但是出现了这样的错误，还请大家给与指正？
参数“3”必须与关键字“ref”一起传递
谢谢了先~！
