unity连接MySql所需要的dll.unitypackage
Unity Hololens可以使用.NET的MySQL连接器库进行MySQL数据库连接。以下是一些步骤:
1. 安装MySQL Connectors for .NET。您可以从这里下载:https://dev.mysql.com/downloads/connector/net/
2. 在Unity项目中创建一个C#脚本
3. 在脚本中,使用MySQL Connectors for .NET建立MySQL数据库连接并执行查询。以下是一个简单的示例:
```csharp
using System.Data;
using MySql.Data.MySqlClient;
public class DatabaseManager : MonoBehaviour {
private MySqlConnection connection;
private string server = "localhost";
private string database = "mydatabase";
private string uid = "myusername";
private string password = "mypassword";
void Start () {
string connectionString = "SERVER=" + server + ";" + "DATABASE=" +
database + ";" + "UID=" + uid + ";" + "PASSWORD=" + password + ";";
connection = new MySqlConnection(connectionString);
try {
connection.Open();
Debug.Log("MySQL Connection State: " + connection.State);
} catch (MySqlException ex) {
Debug.Log("MySQL Error: " + ex.ToString());
}
}
void OnApplicationQuit() {
if (connection != null) {
connection.Close();
Debug.Log("MySQL Connection State: " + connection.State);
}
}
public void SelectQuery() {
MySqlCommand cmd = connection.CreateCommand();
cmd.CommandText = "SELECT * FROM mytable";
MySqlDataReader dataReader = cmd.ExecuteReader();
while (dataReader.Read()) {
Debug.Log("Column 1: " + dataReader[0] + ", Column 2: " + dataReader[1]);
}
dataReader.Close();
}
}
```
在上面的示例中,我们在Start函数中建立MySQL数据库连接,并在OnApplicationQuit函数中关闭连接。我们还创建了一个SelectQuery函数来执行查询并打印结果。
请注意,您需要将server,database,uid和password变量替换为您的MySQL服务器详细信息。
希望这可以帮助您开始连接MySQL数据库与Unity Hololens。
