wpf将表中数据显示到datagrid示例

a.在.xaml文件中拖入一个datagrid,然后添加列名，使用Binding="{Binding 数据库中的列名称}"，如下： 

<DataGrid AutoGenerateColumns="False" Height="438"HorizontalAlignment="Left" Margin="23,278,0,0" Name="dataGrid1"  VerticalAlignment="Top" Width="1249">           

    <DataGrid.Columns>               

    <DataGridTextColumn Width="100" FontSize="15" Header="编号" Binding="{Binding id}"/>                          

    <DataGridTextColumn Width="140" Header="名称" FontSize="15"  Binding="{Binding name}"/>               

     </DataGrid.Columns>       

</DataGrid>

b.首先把要显示的数据查询后放入datatable中  

public DataTable Show()
{           
DataTable dt = new DataTable();           
try           
{
if (DBHelper.connection.State == ConnectionState.Closed)                   
DBHelper.connection.Open();               
string sql = "查询语句";               
DataSet ds = new DataSet();               
SqlDataAdapter sda = new SqlDataAdapter(sql,DBHelper.connection);               
sda.Fill(ds, "虚拟表名");               
dt= ds.Tables["虚拟表名"];           
}           
catch (Exception ex)           
{               
MessageBox.Show(ex.Message);           
}           
return dt;       
}
//注意：该方法中的虚拟表名就是一个自己定义的表名称
c.然后在后台代码编辑处将datatable中的数据与datagrid绑定 
dataGrid1.ItemsSource = Show().DefaultView;
