wpf 计算器布局练习

先看一下windows自带计算机的布局：

大概布局能看出，有菜单栏（menu），有显示框（textbox），然后剩下的6行5列的布局

先看下代码：

            <StackPanel>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition></RowDefinition>
                    </Grid.RowDefinitions>
                    <TextBox Name="xianshi" Text="显示框" Height="50" Margin="5,5,5,5"></TextBox>
                </Grid>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                        <RowDefinition></RowDefinition>
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition></ColumnDefinition>
                        <ColumnDefinition></ColumnDefinition>
                        <ColumnDefinition></ColumnDefinition>
                        <ColumnDefinition></ColumnDefinition>
                        <ColumnDefinition></ColumnDefinition>
                    </Grid.ColumnDefinitions>
                    <Button Grid.Row="0" Grid.Column="0" Content="MC" Margin="5"></Button>
                    <Button Grid.Row="0" Grid.Column="1" Content="MR" Margin="5"></Button>
                    <Button Grid.Row="0" Grid.Column="2" Content="MS" Margin="5"></Button>
                    <Button Grid.Row="0" Grid.Column="3" Content="M+" Margin="5"></Button>
                    <Button Grid.Row="0" Grid.Column="4" Content="M-" Margin="5"></Button>

                    <Button Grid.Row="1" Grid.Column="0" Content="←" Margin="5"></Button>

                    <Button Grid.Row="1" Grid.Column="3" Content="±" Margin="5"></Button>
                    <Button Grid.Row="1" Grid.Column="4" Content="√" Margin="5"></Button>

                    <Button Grid.Row="2" Grid.Column="0" Content="7" Margin="5"></Button>
                    <Button Grid.Row="2" Grid.Column="1" Content="8" Margin="5"></Button>
                    <Button Grid.Row="2" Grid.Column="2" Content="9" Margin="5"></Button>
                    <Button Grid.Row="2" Grid.Column="3" Content="/" Margin="5"></Button>
                    <Button Grid.Row="2" Grid.Column="4" Content="%" Margin="5"></Button>

                    <Button Grid.Row="3" Grid.Column="0" Content="4" Margin="5"></Button>
                    <Button Grid.Row="3" Grid.Column="1" Content="5" Margin="5"></Button>
                    <Button Grid.Row="3" Grid.Column="2" Content="6" Margin="5"></Button>
                    <Button Grid.Row="3" Grid.Column="3" Content="*" Margin="5"></Button>
                    <Button Grid.Row="3" Grid.Column="4" Content="1/x" Margin="5"></Button>

                    <Button Grid.Row="4" Grid.Column="0" Content="1" Margin="5"></Button>
                    <Button Grid.Row="4" Grid.Column="1" Content="2" Margin="5"></Button>
                    <Button Grid.Row="4" Grid.Column="2" Content="3" Margin="5"></Button>
                    <Button Grid.Row="4" Grid.Column="3" Content="-" Margin="5"></Button>
                    <Button Grid.Row="4" Grid.Column="4" Content="=" Grid.RowSpan="2" Margin="5"></Button>

                    <Button Grid.Row="5" Grid.Column="0" Content="0" Grid.ColumnSpan="2" Margin="5"></Button>

                    <Button Grid.Row="5" Grid.Column="2" Content="." Margin="5"></Button>
                    <Button Grid.Row="5" Grid.Column="3" Content="+" Margin="5"></Button>

                </Grid>
            </StackPanel>
        </DockPanel>

看下生成的结果：

虽然还差了点，但是继续努力吧。。。继续学习。。
