为dll程序集存储数据的更好解决方案

// DLL中的代码
public static class DataStore {
    public static int SharedData { get; set; }
}

// DLL中的代码
public class ConfigReader {
    public static void LoadConfig(string filePath) {
        var config = File.ReadAllText(filePath);
        // 解析配置并存储到全局变量或静态变量中
    }
}

// DLL中的代码
public class DatabaseHelper {
    private static SqlConnection connection;

    public static void Initialize(string connectionString) {
        connection = new SqlConnection(connectionString);
    }

    public static void SaveData(string key, string value) {
        using (var cmd = new SqlCommand("INSERT INTO DataTable (Key, Value) VALUES (@Key, @Value)", connection)) {
            cmd.Parameters.AddWithValue("@Key", key);
            cmd.Parameters.AddWithValue("@Value", value);
            connection.Open();
            cmd.ExecuteNonQuery();
            connection.Close();
        }
    }
}

// DLL中的代码
public class MemoryMappedFileHelper {
    private static MemoryMappedFile mmf;

    public static void CreateOrOpen(string name, long capacity) {
        mmf = MemoryMappedFile.CreateOrOpen(name, capacity);
    }

    public static void WriteData(long offset, byte[] data) {
        using (var accessor = mmf.CreateViewAccessor(offset, data.Length)) {
            accessor.WriteArray(0, data, 0, data.Length);
        }
    }

    public static byte[] ReadData(long offset, int length) {
        byte[] data = new byte[length];
        using (var accessor = mmf.CreateViewAccessor(offset, length)) {
            accessor.ReadArray(0, data, 0, length);
        }
        return data;
    }
}

// 使用锁机制
private static readonly object lockObject = new object();
public static void SafeWriteData(string key, string value) {
    lock (lockObject) {
        // 写入数据的代码
    }
}

// 使用缓存机制
private static Dictionary<string, string> cache = new Dictionary<string, string>();
public static string GetCachedData(string key) {
    if (cache.ContainsKey(key)) {
        return cache[key];
    }
    // 从数据库或其他数据源读取数据并缓存
    string data = ReadFromDatabase(key);
    cache[key] = data;
    return data;
}
