iif-function

问题 I have worked on only possible 2 in rdlc Expression values as like =iif((Fields!Gender.Value="1"),"Male","Female") Here I can work with only 2 possibilities. But if I want to check 3 or more conditions than how can I? 回答1: Use the Switch if you have more conditions, it is also more readable. =Switch( Fields!Gender.Value = 1, "Male", Fields!Gender.Value = 2, "Female" ) rdlc expression iif use? 回答2: You can use the Code property of the report. Right-click a blank space outside your report and

问题 the question is simple, there is a functional equivalent of the famous iif in java? For example: IIf (vData = "S", True, False) Thanks in advance. 回答1: vData.equals("S") ? true : false or in this particular case obviously one could just write vData.equals("S") 回答2: Yeah, the ternary op ? : vData.equals("S") ? true : false 回答3: The main difference between the Java ternary operator and IIf is that IIf evaluates both the returned value and the unreturned value, while the ternary operator short

问题 I recently asked a question about IIf vs. If and found out that there is another function in VB called If which basically does the same thing as IIf but is a short-circuit. Does this If function perform better than the IIf function? Does the If statement trump the If and IIf functions? 回答1: Damn, I really thought you were talking about the operator all along. ;-) Anyway … Does this If function perform better than the IIf function? Definitely. Remember, it's built into the language. Only one

问题 Is there a IIf equivalent in C# ? Or similar shortcut? 回答1: C# has the ? ternary operator, like other C-style languages. However, this is not perfectly equivalent to IIf() ; there are two important differences. To explain the first difference, the false-part argument for this IIf() call causes a DivideByZeroException , even though the boolean argument is True . IIf(true, 1, 1/0) IIf() is just a function, and like all functions all the arguments must be evaluated before the call is made. Put

问题 The following works: If 1=1 rdoYes.checked = True Else rdoNo.checked = True End If However, the following doesn't work: IIF(1=1, rdoYes.checked = True, rdoNo.checked = True) Why is this? Thanks! 回答1: It does "work"; it just doesn't do what you want. IIf in VB.NET is a function (don't use it, ever, by the way), which takes these parameters: A Boolean condition to check An Object to return if the condition is True A different Object to return if the condition is False In your usage, your

问题 I want my textbox to have an action ONLY if the condition is true, otherwise no action. This is what I have as my current action expression for going to another report: =IIf(Fields!MyTextbox.Value = "0", "Report2","") This does not produce my desired result. It gives the textbox an action regardless of the condition result. Is there a 'No Action' or 'Cancel Action' value? 回答1: The null keyword in VB is Nothing : =IIf(Fields!MyTextbox.Value = "0", "Report2", Nothing) 来源： https://stackoverflow
