代码背后的网格星大小

Question

我有一个网格如下,

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

我如何给出Height = "0.5*"代码？

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);
