? : Operator
-
It means
if (b == null)
a = null;
else
a = a.ToString(); //this rarely makes sense, didn't you mean b.ToString()?But it's an expression instead of a statement.

Thank you , But for a certain things MSDN is Yak ! http://msdn.microsoft.com/en-us/library/ty67wk28.aspx[^]
The conditional operator is right-associative. The expression a ? b : c ? d : e is evaluated as a ? b : (c ? d : e), not as (a ? b : c) ? d : e. The conditional operator cannot be overloaded.X|I know nothing , I know nothing ...
You're right, and that's classic Microsoft - technically accurate, entirely useless information! :laugh:

Hi , have a good day Can anyone Explain for me what the meaning of this ?
a = b == null ? null : a.ToString();
P.S : for more information : I use this component Example Code , and I need to understand it ! http://www.gemboxsoftware.com/help/html/M_GemBox_Spreadsheet_ExcelWorksheet_ExtractToDataTable.htm[^]
if (e.ErrorID == ExtractDataError.WrongType)
{
e.DataTableValue = e.ExcelValue == null ? null : e.ExcelValue.ToString();
e.Action = ExtractDataEventAction.Continue;
}Please , Don't tell to Ask at Component Forum , due my question is C# syntax things thank you

? operator its like a IF-result statement. look:
int x = 0;
int y = 1;if(x > y) ? y++ : y--;
If x>y = true, y++.
If x>y = false, y--;
