I have 6 bool "categories":
Category0, Category1, Category2, Category3, Category4, Category5.
I also have a "String ListCat" variable. This variable must look like something like:
ListCat = "0,1,2,3,4,5"
Where "0" is displayed if Category0 = true, "1" if category1 = true...
For exemple :
Categorie0 = true;
Catgorie1 = true;
Categorie5 = true;
Then ListCat would be like :
ListCat ="0,1,5"
I have to do this to complete this query :
string StSQL = @"SELECT [Type Jour] FROM CodificationTypesJour where Categorie IN (" + ListCat + ");
How can I do that, with the commas included?
Thanks in advance.
You can create an array of values you want to add to result, then join them using String.Join Method .
For example if you have:
bool category0 = true,
category1 = true,
category2 = false,
category3 = false,
category4 = false,
category5 = true;
then you can create an array:
string[] values =
{
category0 ? "0" : null,
category1 ? "1" : null,
category2 ? "2" : null,
category3 ? "3" : null,
category4 ? "4" : null,
category5 ? "5" : null
};
and the result will be:
var result = string.Join(",", values.Where(s => s != null));
// output: "0,1,5"
