如何在Reporting Services表达式语言中编写if else语句？

Question

我想编写一个Reporting Services "Expression"，它基本上表现如下（伪代码）......

if ([Fields!StateProvinceId.Value] == 1)
{
   return "Ontario";
}
else if ([Fields!StateProvinceId.Value] == 2)
{
   return "Quebec";
}
else if ([Fields!StateProvinceId.Value] == 3)
{
   return "Manitoba";
}
// ...
// more cases same pattern

我没有看到这种类型的逻辑是否需要嵌套一堆IIF？

=IIF(Fields!StateProvinceId.Value = 1, "Ontario", IIF(Fields!StateProvinceId.Value = 2, "Quebec", IFF(Fields!StateProvinceId.Value = 3, "Manitoba", "Unknown Province")))

Answer 1

您是否尝试过切换声明？

= Switch( Fields!StateProvinceId.value=1,"Ontario", Fields!StateProvinceId.value=2,"Quebec", Fields!StateProvinceId.value=3,"Manitoba")
