} expected using c# in biml

Question

I'm writing biml in visual studio and have a problem when using c#. I get an error saying "} expected" pointing to the closing bracket of the if statement, but I can't find where I'm missing something. I'm new to this and aware that there are probably other mistakes too :)

Answer 1

First syntax error (not reported)

<Input OutputPathName="Sequence Container_<#previousOrder#>"/>

You're missing a semicolon here or you intended to use <#= here

<Input OutputPathName="Sequence Container_<#=previousOrder#>"/>

The reported error is weird and while I'm not fully awake, I don't see what the root cause is.

My approach was to format your code into what my brain expects with regard to brace placement.

This code still has the error about unmatched {

all I did was eliminate the leading space in front of the directive in the else clause.

Going back to your original version, same thing. So, something in line 17 is making things go haywire but as I don't have a working minimal reproduction, I can't say for certain what you have wrong.

You can also make the error go away with the following but still just bandage over a shotgun wound

                        <#if (order == "0"){#>
                            <Inputs>
                                <Input OutputPathName="Set IDRunMaster.Output"/>
                            </Inputs>
                        <#}else{#>

This isn't python or FORTRAN so whitespace should not be the culprit and yet, here we are
