string sendMessage = "client send Message Hellp" + DateTime.Now;

这段代码定义了一个字符串类型的变量sendMessage，用于存储要发送的消息。该消息是一个字符串，由“client send Message Hellp”和当前时间组成。在实际的应用中，消息内容可以根据具体的需求进行定义，需要注意消息的格式和内容应该符合通信协议的要求。同时，由于消息中包含了时间信息，可以方便地进行消息的排序和处理。

解释 public void SendCharacterCreate(string name, CharacterClass cls) { Debug.LogFormat("UserCreateCharacterRequest::name :{0} class:{1}", name, cls); NetMessage message = new NetMessage(); message.Request = new NetMessageRequest(); message.Request.createChar = new UserCreateCharacterRequest(); message.Request.createChar.Name = name; message.Request.createChar.Class = cls; if (this.connected && NetClient.Instance.Connected) { this.pendingMessage = null; NetClient.Instance.SendMessage(message); } else { this.pendingMessage = message; this.ConnectToServer(); } }

这段代码是一个用于发送创建角色请求的方法。让我逐行解释代码的含义：

public void SendCharacterCreate(string name, CharacterClass cls)

这是一个公共的方法，用于发送创建角色的请求。它接受两个参数：`name` 表示角色名称，`cls` 表示角色类别（CharacterClass 类型）。

Debug.LogFormat("UserCreateCharacterRequest::name :{0} class:{1}", name, cls);

这行代码使用 `Debug.LogFormat` 方法来打印调试信息，显示创建角色请求的名称和类别。

NetMessage message = new NetMessage();
message.Request = new NetMessageRequest();
message.Request.createChar = new UserCreateCharacterRequest();
message.Request.createChar.Name = name;
message.Request.createChar.Class = cls;

这部分代码创建了一个 `NetMessage` 对象，并设置了其中的请求信息。`NetMessage` 是一个自定义的网络消息类，用于封装发送给服务器的请求数据。`NetMessageRequest` 表示具体的请求内容，其中的 `createChar` 是一个 `UserCreateCharacterRequest` 类型的对象，用于存储创建角色请求的细节信息。通过设置 `Name` 和 `Class` 属性，将角色名称和类别赋值给请求对象。

if (this.connected && NetClient.Instance.Connected)
{
    this.pendingMessage = null;
    NetClient.Instance.SendMessage(message);
}
else
{
    this.pendingMessage = message;
    this.ConnectToServer();
}

这段代码检查当前客户端是否已连接到服务器。如果已连接，它将发送封装好的消息对象给服务器，通过调用 `NetClient.Instance.SendMessage(message)` 方法。如果未连接，它将把消息对象存储在 `pendingMessage` 变量中，并调用 `ConnectToServer()` 方法来连接到服务器。

请注意，这段代码假设存在一个名为 `NetMessage` 的类，用于封装网络消息，以及名为 `NetClient` 的类，用于处理与服务器的通信。同时假设存在一个名为 `UserCreateCharacterRequest` 的类，用于存储创建角色请求的细节信息。

请根据你的项目需求和具体实现进行相应的修改和适配。
