在C#中获取唯一标识符的最佳方法

using System.Guid;

// 生成Guid
Guid g = new Guid();

using System.Runtime.InteropServices;

// 生成UUID
string uuid = Guid.NewGuid().ToString();

using System.Data.SqlClient;

// 创建SqlConnection和SqlCommand对象
string connectionString = "connection string here";
SqlConnection sqlConnection = new SqlConnection(connectionString);
SqlCommand sqlCommand = new SqlCommand("SELECT MAX(id) + 1 FROM table_name", sqlConnection);

// 执行SQL语句并获取结果
sqlConnection.Open();
int id = (int)sqlCommand.ExecuteScalar();

// 将自增ID返回给前端或存储到数据库中
return id;
