代码后面的网格星形大小

Question

我有一个网格如下，

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition Height="0.5*" />
        <RowDefinition Height="0.5*" />
    </Grid.RowDefinitions>
</Grid>

如何在后面的代码中给出 Height = "0.5*" ？

Answer 1

您可以使用：

rowDefinition.Height = new GridLength(0.5, GridUnitType.Star);

Answer 2

grid.RowDefinitions[0].Height = new GridLength(0.5, GridUnitType.Star);
