在 Winform 中使用 SqlSugar 首先需要安装 SqlSugar 包,可以通过 NuGet 包管理器搜索并安装 SqlSugar。

using SqlSugar;  public class DatabaseContext {     private SqlSugarClient db;      public DatabaseContext()     {         db = new SqlSugarClient(new ConnectionConfig()         {             ConnectionString = "YourConnectionString",             DbType = DbType.SqlServer,             IsAutoCloseConnection = true         });     }      public List<T> GetAll<T>() where T : class, new()     {         return db.Queryable<T>().ToList();     }      public T GetById<T>(object id) where T : class, new()     {         return db.Queryable<T>().InSingle(id);     }      public void Insert<T>(T entity) where T : class, new()     {         db.Insertable(entity).ExecuteCommand();     }      public void Update<T>(T entity) where T : class, new()     {         db.Updateable(entity).ExecuteCommand();     }      public void Delete<T>(T entity) where T : class, new()     {         db.Deleteable(entity).ExecuteCommand();     } } 

在 Winform 窗体中使用 DatabaseContext 类来进行数据库操作:

private void btnGetAll_Click(object sender, EventArgs e) {     DatabaseContext dbContext = new DatabaseContext();     var data = dbContext.GetAll<YourEntity>();     dataGridView.DataSource = data; }  private void btnInsert_Click(object sender, EventArgs e) {     DatabaseContext dbContext = new DatabaseContext();     YourEntity entity = new YourEntity { Name = "Test" };     dbContext.Insert(entity); }  private void btnUpdate_Click(object sender, EventArgs e) {     DatabaseContext dbContext = new DatabaseContext();     YourEntity entity = dbContext.GetById<YourEntity>(1);     entity.Name = "Updated";     dbContext.Update(entity); }  private void btnDelete_Click(object sender, EventArgs e) {     DatabaseContext dbContext = new DatabaseContext();     YourEntity entity = dbContext.GetById<YourEntity>(1);     dbContext.Delete(entity); } 

在上面的代码中,需要将 “YourConnectionString” 替换为实际的数据库连接字符串,以及将 “YourEntity” 替换为实际的实体类名称。通过 DatabaseContext 类的方法实现数据库的增删改查操作,并在 Winform 窗体的按钮点击事件中调用这些方法来操作数据库。
