如果C#中的length属性声明

Question

在C#中,if语句我正在捕获length属性并希望为此应用条件语句.但我相信我的条件声明不起作用.我应该如何为给定的代码应用条件语句.长度"66"表示互联网连接已关闭,否则将其启动.

WebClient client = new WebClient();
string value;
try
{
    value = client.DownloadString("http://google.com");
}
catch(WebException ex)
{
    value = (ex. Message);
}
if (value = "66")
{
    Console.WriteLine("Internet connection is down");
}
else
{
    Console.WriteLine("Internet connection is up");
}
Console.WriteLine(value.Length);           
Console.WriteLine("Press any key to continue");
Console.ReadKey(true);

Answer 1

value = "66"是一种赋值,而不是一种相等的比较value == "66".
