当前上下文中不存在名称“lblbtcaount” [英] The name 'lblbtcaount' does not exist in the current context

问题描述

错误显示 -

当前上下文中不存在名称'lblbtcaount'



我尝试了什么：



if（ds2.Tables [0] .Rows.Count> 0）

{

userid = Convert.ToString（ds2.Tables [0] .Rows [0] [userid]）;

lblbtcaount.Text = Convert.ToString（ds2.Tables [0] .Rows [0] [bitcoinval]）; //此行错误显示



imgpath = Convert.ToString（http://www.g.com/+ ds2.Tables [0] .Rows [0] [macadd]）;

}

Error is show-
The name 'lblbtcaount' does not exist in the current context

What I have tried:

if (ds2.Tables[0].Rows.Count > 0)
{
userid = Convert.ToString(ds2.Tables[0].Rows[0]["userid"]);
lblbtcaount.Text = Convert.ToString(ds2.Tables[0].Rows[0]["bitcoinval"]); // This line error show

imgpath = Convert.ToString("http://www.g.com/" + ds2.Tables[0].Rows[0]["macadd"]);
}

推荐答案

错误非常明确：

The error is pretty explicit:

The name 'lblbtcaount' does not exist in the current context

它意味着它所说的：当前类或方法中没有任何内容称为 lblbtcaount - 要么你有错误的类，错误的拼写，要么错误的情况：C＃区分大小写，所以 lblbtcaount 不是sa我是 lblbtCaount 。

但我猜它是拼写：你的意思是 lblbtcount 而不是？

It means what it says: there is nothing in the current class or method called lblbtcaount - either you have the wrong class, the wrong spelling, or the wrong case: C# is case sensitive, so lblbtcaount is not the same as lblbtCaount.
But I'd guess that it's the spelling: did you mean lblbtcount instead?
