Returning a single row in a strongly typed DataSet in C#

Question

我在C＃中有一个强类型数据集TableAdapter，如何从中获取单行？

Answer 1

var table = tableAdapter.GetData();
var resultRow = table.Rows[0];

EDIT: Strongly-typed datasets create a property for each column in the table, so to get the Id, this should work:

int id = resultRow.Id

You can also get fields by name:

int id = (int)resultRow["id"];

Answer 2

你可以试试：

myTableAdapter[0];

Answer 3

       var ta = new AddressTableAdapter();

       var ret = ta.GetDataBy(Convert.ToInt32(ASPxTextBox1.Text));
       var rw = ret.Rows[0];

       var city = (string)rw["City"];


       ASPxTextBox2.Text = city.ToString();

Answer 4

You can also create an additional parameterized query (ie 'WHERE ID = @id') and call that instead of the default GetData method:

var table = tableAdapter.GetDataById(123); 
var resultRow = table.Rows.First;
