Question

帮忙看一下这段c#代码有什么问题,提示说当前上下文中不存在名称lblStatus,这是什么问题…………谢了……

{
static string[,] userList;
fileOperation fs ;

protected void Page_Load(object sender, EventArgs e)
{
ArrayList r;
int i = 0;
if (!IsPostBack)
{
fs = new fileOperation();
r =fs.getAllUser() ;
userList=new string[r.Count,3];
foreach (string strout in r)
{

char[] ch = new char[] { ',' };//分隔条件
string[] str;
str = strout.Split(ch);
for (int j = 0; j < 3; j++)
{
userList[i, j] = str[j];

}
i = i + 1;
}
}
}
protected void btnRegister_Click(object sender, EventArgs e)
{
//判断用户名是否已经注册
for (int i = 0; i < userList.Length / 3; i++)
{
if (txtUserName.Text.Trim() == userList[i, 0])
{
lblStatus.Text = "此用户名已经注册！";
return;
}

}
}

protected void btnLogin_Click(object sender, EventArgs e)
{
Response.Redirect("login.aspx");
}
}

从代码看应该就是界面上的一个Lable控件，名称为“lblStatus”，检查一下是不是没有添加这个控件。希望对你有帮助，有疑问请追问或是Hi
