C#

private void Apply_Filter(ref ReportDocument oRpt)
        {
            string str = "";
            string str2 = "XWV_RPT_REQLIST";
            str = str + " {" + str2 + ".REQNBR}=" + this.ReqNbr.ToString();
            str = str + " And {" + str2 + ".L_Language_Id}=\"" + Conversions.ToString(this.oUser.LANGUAGE_ID) + "\"";
            ReportDocument document = oRpt;
            document.set_RecordSelectionFormula(document.get_RecordSelectionFormula() + str);
            oRpt.Refresh();
        }

Error is coming on the below line

C#

str = str + " And {" + str2 + ".L_Language_Id}=\"" + Conversions.ToString(this.oUser.LANGUAGE_ID) + "\"";

Any inputs? Please

Are you sure that is the line? According to, https://msdn.microsoft.com/en-us/library/microsoft.visualbasic.compilerservices.conversions.tostring(v=vs.80).aspx, Conversions.ToString() has, at least since .Net 2.0, always taken 1 argument.

I'd right click on Conversions and choose "Go To Definition" and see where it takes you. It sounds like you have the wrong version loaded or a custom version perhaps.

You are right. Error is coming in the line after that

document.set_RecordSelectionFormula(document.get_RecordSelectionFormula() + str);

But this line won't give the .ToString() error because there is no .ToString() in that line, unless you step into set_RecordSelectionFormula. I believe you need to step into that function. Or in the get_RecordSelectionFormula() function. But keep digging to find the exact piece of code causing the issue and then you'll likely see what the problem is.

Do you mean

C#

... Convert.ToString(this.oUser.LANGUAGE_ID) ...

instead of

C#

... Conversions.ToString(this.oUser.LANGUAGE_ID) ...
