如果使用的是mvvm模式的话，可以像下面这么做：

xaml：<UserControl x:Class="CustomSetSN"             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"              xmlns:local="clr-namespace:Customer.MvvM"             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"              mc:Ignorable="d"              d:DesignHeight="340" d:DesignWidth="538">    <UserControl.DataContext>        <local:CViewModel/>    </UserControl.DataContext>    <Grid Background="#FF7EDE75">        <Grid.RowDefinitions>            <RowDefinition Height="81*"/>            <RowDefinition Height="89*"/>        </Grid.RowDefinitions>        <DataGrid x:Name="dataGrid1" Background="#FF7EDE75" AutoGenerateColumns="False" CanUserAddRows="False"  HeadersVisibility="Column" HorizontalAlignment="Left" Margin="-7,-6,-3,0" VerticalAlignment="Top" Width="548" Height="346"  Loaded="ItemsSources_Load" Grid.RowSpan="2">            <DataGrid.ColumnHeaderStyle>                <Style TargetType="{x:Type DataGridColumnHeader}">                    <Setter Property="HorizontalContentAlignment" Value="Center" />                </Style>            </DataGrid.ColumnHeaderStyle>            <DataGrid.Columns >                <DataGridTextColumn Header="设备总编号" x:Name="curtainEquTotalNum" Width="19*" Binding="{Binding EquTotalNum,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" IsReadOnly="True"/>            </DataGrid.Columns>        </DataGrid>    </Grid></UserControl>后台函数中可以这样写: var selectItem = dataGrid1.SelectedItem as SmartDbViewModel;//!根据点击的item获取集合中的数据string currentChoicEquT = selectItem.EquTotalNum.ToString();mvvm中EquTotalNum实现方式:  public string EquTotalNum        {            get { return _EquTotalNum; }            set            {                if (_EquTotalNum != value)                {                    _EquTotalNum = value;                    RaisePropertyChanged("EquTotalNum");                }            }        }

其他的一样的获取。
