Errors in my C# plugin

Code:

// Reference: Oxide.Ext.Rustnamespace Oxide.Plugins
{
    [Info("Welcomehelp", "PEPE", "0.1.0", ResourceId = 681)]
    public class PluginName : RustPlugin
    {
      void OnPlayerConnected(Network.Message packet)
        {
            var message = "HELLO~: <color=lime> /event_join";
            rust.SendChatMessage({ player, message });
        }
    }
}

its my code
what`s wrong? i got an error when i put in this plugin at my server

PM [Error] Plugin filename is incorrect: welcomehelp.cs

 

The filename must match the name of the class.

 

then i got a new error

[Error] Failed to load plugin 'welcomekit' (no source found)

 

public class PluginName : RustPlugin => public class welcomekit : RustPlugin

 

Your next error will be rust.SendChatMessage({ player, message });

 

=> rust.SendChatMessage( player, message );

 

it`s still not working

 

rust.SendChatMessage(player, message, "0");
or you can do player.ChatMessage(message)

 

Oh? Back when I was playing with that one I would get an error if I didn't specify the userid. But that was a while ago

 

Still got a terrible error
[Error] Plugin filename is incorrect: welcomehelp.cs

Here is my code

Code:

// Reference: Oxide.Ext.Rustnamespace Oxide.Plugins
{
    [Info("Welcomehelp", "PEPE", "0.1.0", ResourceId = 681)]
    public class welcomehelp : RustPlugin
    {
      void OnPlayerConnected(Network.Message packet)
        {
            var message = "TEST: <color=lime> /event_join";
            rust.SendChatMessage(player, message, "0");
        }
    }
}

 

is your filename Welcomehelp or welcomehelp. your filename needs to be the same as the plugin name in the code. It is case sensitive.

 

its same "welcomehelp.cs"

 

i got a new error

[Error] Error while compiling WelcomeHelp.cs(11,4): error CS0103
: The name `rust' does not exist in the current context

 

You can't use rust.SendChatCommand without importing the correct namespace, that being said, all those rust._____ methods are helpers for Py, Lua and JS plugins. For C# there is a different set of helpers available -> https://github.com/OxideMod/Oxide/blob/master/Oxide.Ext.Rust/RustPlugin.cs#L146
