RDLC表达式Switch使用？ [英] RDLC expression Switch use?

问题描述

=Switch(
    Fields!C2.Value = "","",
    Fields!C2.Value > 0,Fields!SeqNo.Value
    )

这是什么语法？





我不会比较变量如

What is the syntax for this?


I wont to compare variable like

if(C2 ==" ")
   {
    C2.Value = empty
   }
   else
   {
    C2.Value = Fields!SeqNo.Value
   }

推荐答案

您的代码似乎没问题，但如果两个条件都不匹配怎么办？我已经为最终条件添加了默认值。

your code seems OK but what if both conditions not match? I have added default value for final condition.

=Switch(
    IsNumeric(Fields!C2.Value) and  Fields!C2.Value > 0, Fields!SeqNo.Value,
    1=1, Fields!C2.Value
    )

更新：


以下
：

UPDATE:

for below:

if(C2 ==" ")
   {
    C2.Value = empty
   }
   else
   {
    C2.Value = Fields!SeqNo.Value
   }

尝试

try

=Switch(
    Fields!C2.Value = " ", "",
    1=1, Fields!C2.Value
    )
