网格星号在后面的代码

我有一个网格如下，

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

我如何在代码中给出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);
