WPF中1颗星（GridUnitType.Star）有多少像素

Question

我在这里找到了

var gridLength = new GridLength(1, GridUnitType.Star);

我想知道，1 星 = ?像素

在互联网上联系到我，但我找不到任何关于此的线索

谢谢。

Answer 1

star是相对单位，类似于css中的%，但略有不同

//will split the grid into two columns with equal width
<ColumnDefinition Width="1*" /> //the same as Width="*"
<ColumnDefinition Width="1*" />


//will split the grid into two columns with ratio 1:2 
<ColumnDefinition Width="1*" />
<ColumnDefinition Width="2*" />

//will split the grid into two columns, first 50px (fixed), second the rest of the grid
<ColumnDefinition Width="50" />
<ColumnDefinition Width="*" />

//will split the grid into three columns, first 50px, and the rest of the grid splitted with ratio 2:2, which is the same as 1:1
<ColumnDefinition Width="50" /> 
<ColumnDefinition Width="2*" />
<ColumnDefinition Width="2*" />
