eidtpassword.aspx.cs

if (uploadsuccesbesked.uploadindhold("succes"))         {             panelindhold.visible = true;             literalbesked.text = /*tekst come here*/;         } 

error message:

cannot implicitly convert type 'uploadsuccesbesked.validationresponse' 'bool'

the reason have written text come here, example in success, text in danish become listed here.

this signature of method:

public static validationresponse uploadindhold(string trueindhold) //            ^^^^^^^^^^^^^^^^^^ 

and underlined part return type. method returns object of type (or null).

in check, this:

if (uploadsuccesbesked.uploadindhold("succes")) 

this tries convert return value of method (which validationresponse object per above) bool, because if statements expect boolean value condition. of course not work.

what should instead check whether return value null. , if save return value, can reuse text:

validationresponse result = uploadsuccesbesked.uploadindhold("succes"); if (result != null) {     panelindhold.visible = true;     literalbesked.text = result.tekst; }
