Or change StackPanel to Grid
或将 StackPanel 更改为 Grid
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="LightGray"
Title="Window1" Height="350" Width="700" >
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="auto" />
<RowDefinition Height="auto" />
<RowDefinition Height="1*" />
</Grid.RowDefinitions>
<Menu>
<MenuItem Header="Find" x:Name="gMNuFind" />
</Menu>
<Button Grid.Row="1" Content=" Find "
Margin="5,10,5,5"
x:Name="gBuFind"
/>
<TextBox Grid.Row="2" Margin="0,0,0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
MinHeight="270" MinWidth="690"
x:Name = "gTBxInfo"
TextWrapping="Wrap"
AcceptsReturn="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
/>
</Grid>
</Window>

Remove MinHeightand MinWidthfrom the TextBox, and change HorizonalAlignmentto Stretch
删除MinHeight和MinWidth从TextBox，并改变HorizonalAlignment以Stretch
<TextBox Margin="0,0,0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Top"
x:Name = "gTBxInfo"
TextWrapping="Wrap"
AcceptsReturn="True"
ScrollViewer.VerticalScrollBarVisibility="Auto" />
Edit:
编辑：
If you want to resize the TextBoxin both directions (horizontally and vertically), you would have to use a different container other than StackPanel, so that the TextBoxsizing is independent.
如果要TextBox在两个方向（水平和垂直）调整 的大小，则必须使用 以外的其他容器StackPanel，以便TextBox调整大小是独立的。
Something like this:
像这样的东西：
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="50"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<Menu>
<MenuItem Header="Find" x:Name="gMNuFind" Grid.Row="0"/>
</Menu>
<Button x:Name="gBuFind"
Content=" Find "
Margin="5,10,5,5"
Grid.Row="1"/>
<TextBox x:Name = "gTBxInfo"
Margin="0,0,0,0"
HorizontalAlignment="Stretch"
VerticalAlignment="Stretch"
TextWrapping="Wrap"
AcceptsReturn="True"
ScrollViewer.VerticalScrollBarVisibility="Auto"
Grid.Row="2"/>
</Grid>
