如何检查CacheConnection是否失败

Question

我有以下C＃：

string Connectioncacha = "";

CacheConnection CacheConnect = new CacheConnection();
CacheConnect.ConnectionString = Connectioncacha;
CacheConnect.Open();

if (CacheConnect.State == ConnectionState.Open)
{
    return "working";
}
else
{
    return "no data";
}

问题是，如果连接失败，它会在CacheConnect.Open()失败并抛出错误。

如何修改代码，以防万一连接失败，而不是显示页面错误，它只是将文本no data发送回客户端？

使用try / catch语句包围它

    try 
    {
      string Connectioncacha = "";

      CacheConnection CacheConnect = new CacheConnection();
      CacheConnect.ConnectionString = Connectioncacha;
      CacheConnect.Open();

    } 
    catch (Exception e)
    {

       if (CacheConnect)
           CacheConnect.Close();
    }
