[英]Missing method exception in .net core
I think this may have something to do with the dependencies, but I'm not really sure. 我认为这可能与依赖关系有关,但我不确定。
So I'm trying to check to see if a TCP connection is still active using the extension method I found here , but I'm getting a missing method exception: 因此,我尝试使用在这里找到的扩展方法来检查TCP连接是否仍处于活动状态,但是我遇到了一个缺少的方法异常:
"Method not found: 'System.Net.IPEndPoint System.Net.NetworkInformation.TcpConnectionInformation.get_LocalEndPoint()'" “找不到方法:'System.Net.IPEndPoint System.Net.NetworkInformation.TcpConnectionInformation.get_LocalEndPoint()'”
Which I'm a little confused on since the method seems to exist . 由于该方法似乎存在,对此我有些困惑。
Here's the code: 这是代码:
public static TcpState GetState(this TcpClient tcpClient)
{
var status = IPGlobalProperties.GetIPGlobalProperties()
.GetActiveTcpConnections()
.SingleOrDefault(x => x.LocalEndPoint.Equals(tcpClient.Client.LocalEndPoint));
return status != null ? status.State : TcpState.Unknown;
}
and the JSON file where I think there might be a problem in how NetworkInformation is referenced: 我认为在引用NetworkInformation时可能存在问题的JSON文件:
{
"buildOptions": {
"debugType": "portable",
"emitEntryPoint": true
},
"frameworks": {
"netcoreapp1.0": {
"dependencies": {
"Microsoft.NETCore.App": {
"type": "platform",
"version": "1.0.0"
}
},
"imports": "dnxcore50"
}
},
"dependencies": {
"system.net.networkinformation": "4.0.10-beta-23123"
},
"version": "1.0.0-*"
}
Am I on the right track? 我在正确的轨道上吗? How would I fix it? 我该如何解决?
Try adding system.net.security
package also, as system.net.networkinformation
depends on security package. 也尝试添加system.net.security
软件包,因为system.net.networkinformation
取决于安全软件包。 It might not have loaded dependencies automatically. 它可能没有自动加载依赖项。
