Vb.net SSRS-使用带有“的表达式”；如果；语句和多个参数值

因此，我试图在SSRS中为一个包含4个用户参数字段的报告设置一些动态文本，但我一直遇到相同的错误。我对SSRS和visualbasic还很陌生，所以理解错误消息有点困难

System.Web.Services.Protocols.SoapException: The Value expression for the textrun 
‘Textbox2.Paragraphs[2].TextRuns[1]’ contains an error: [BC33104] 'If' operator
requires either two or three operands.

4个参数字段是beginYear、beginMonth、endYear和endMonth。以下是表达式中的代码：

If (bYear = eYear) And (bMonth = 1) And (eMonth = 3)
"3rd Quarter January - March " & eYear

ElseIf  (bYear = eYear) And (bMonth = 4) And (eMonth = 6)
"4th Quarter April - June " & eYear

ElseIf  (bYear = eYear) And (bMonth = 7) And (eMonth = 9)
"1st Quarter July - September " & eYear

ElseIf  (bYear = eYear) And (bMonth = 10) And (eMonth = 12)
"2nd Quarter October - December " & eYear

ElseIf  (bYear = eYear) And (bMonth = 1) And (eMonth = 12)
"Calendar Year " & eYear

ElseIf  (bYear = eYear) And (bMonth = eMonth)
eYear & " " & eMonth 

ElseIf  (((Convert.toInt32(bYear)) = (Convert.toInt32(eYear)) - 1) And (((Convert.toInt32(eYear)) = (Convert.toInt32(bYear)) + 1) And (bMonth = 7) And (eMonth = 6)
"Fiscal Year " & bYear & "-" & eYear

Else
             bMonth & " " & bYear & "-" & eMonth & " " & eYear
End If

因此，如果我从报告中选择以下参数，如下所示（在月参数中，我为月指定了数值）：

我应该在报告文本框中看到以下表达式=>“2018年4月至6月第四季度”

这不是SSRS中的

If

格式。见下文：

=Iif(Parameters!yourParameter.Value = Parameters!yourAnotherParameter.Value, "value if true", "value if false")

对于您的情况，您应该使用

开关

=Switch(Parameters!yourParameter.Value = Parameters!yourAnotherParameter.Value 
        AndAlso Parameters!yourParameter.Value = "something else"
        AndAlso Parameters!yourParameter.Value = "again something else", "desired output if all condition are met", 
        Parameters!yourNextParameter.Value = Parameters!yourNextAnotherParameter, "desired output if this condition is met")

尝试添加然后语句。。。（eMonth=3）然后。。。（eMonth=6）然后。。。etcI认为在两个皈依者面前都有一个额外的括号。你的一年不是已经是整数了吗？为什么不呢<代码>（（Convert.toInt32（bYear））=（Convert.toInt32（eYear））-1和（（Convert.toInt32（eYear））=（Convert.toInt32（bYear））+1和（bmmonth=7）和（eMonth=6）我认为您的开关语法不正确。比较之后，如果结果为真，则应该有结果-可能是`…和其他参数！yourParameter.Value=“又是另一个”、“旧的”、“旧的”。公平地说，他确实提到了VB（虽然含糊不清）。感谢你指出这一点，我在我的示例的第一部分中添加了不止一个条件，这让我感到困惑。

=Switch(Parameters!yourParameter.Value = Parameters!yourAnotherParameter.Value 
        AndAlso Parameters!yourParameter.Value = "something else"
        AndAlso Parameters!yourParameter.Value = "again something else", "desired output if all condition are met", 
        Parameters!yourNextParameter.Value = Parameters!yourNextAnotherParameter, "desired output if this condition is met")
