如何用Reporting Services表达式语言编写if else语句? [英] How do I write an if else statement in Reporting Services expression language?

问题描述

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

I would like to write a Reporting Services "Expression" that basically behaves as the following (pseudo code)...

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

我看不到这种逻辑，我是否必须嵌套一堆IIF?

I don't see this type of logic do I have to nest a bunch of IIF?

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

推荐答案

您是否尝试过switch语句?

Have you tried a switch statement?

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