在 Visual Studio 上，我可以通过以下方式创建我的 SQLite 数据库的 DataSet:

1) 连接sqlite数据库文件并创建表

2) 将新数据集添加到我的解决方案 (DataSet2.xsd)

3) 将表格拖到设计器中

现在如何使用 Visual Studio 为我创建的对象?

例如，我正在尝试做类似的事情:

 DataSet2.TableTestDataTable t = new DataSet2.TableTestDataTable();var objects = t.GetObjectData(..//不知道怎么用

或

 DataSet2TableAdapters.TableTestTableAdapter t = new DataSet2TableAdapters.TableTestTableAdapter();var 数据 = t.GetData();var q = 来自数据中的 a选择一个;foreach(q 中​​的 DataSet2.TableTestRow 行){行.整数 = 12345;//改变列整数的值}t.submitchanges();//方法确实注意存在

 DataSet2TableAdapters.TableTestTableAdapter t = new DataSet2TableAdapters.TableTestTableAdapter();DataSet2 ds = new DataSet2();t.Fill(ds.TableTest);foreach(ds.TableTest.Rows 中的 DataSet2.TableTestRow 行){行.整数 = 12345;//改变列整数的值}t.更新(ds2)；

类似的东西......

On visual studio I can create a DataSet of my SQLite database by doing:

1) Connect to sqlite database file and create a table

2) Add new DataSet to my solution (DataSet2.xsd)

3) Drag tables to the designer

Now how can I make use of the objects that visual studio created for me?

for example I am trying to do something like:

        DataSet2.TableTestDataTable t = new DataSet2.TableTestDataTable();
        var objects = t.GetObjectData(..// do not know how to use it

OR

        DataSet2TableAdapters.TableTestTableAdapter t = new DataSet2TableAdapters.TableTestTableAdapter();
        var data = t.GetData(); 

        var q = from a in data
                select a;

        foreach (DataSet2.TableTestRow row in q)
        {
            row.integer = 12345; // change value of column integer               
        }
        t.submitchanges(); // method does note exists

    DataSet2TableAdapters.TableTestTableAdapter t = new DataSet2TableAdapters.TableTestTableAdapter();

    DataSet2 ds = new DataSet2();
    t.Fill(ds.TableTest); 

    foreach (DataSet2.TableTestRow row in ds.TableTest.Rows)
    {
        row.integer = 12345; // change value of column integer               
    }

    t.Update(ds2);

Something like that ....
