C# 2 列表不匹配

Question

`

List<Object> rollerliste = (from row in roller.AsEnumerable() select (row["rolName"])).ToList();
List<Object> yetkiliste  = (from row in roller.AsEnumerable() select (row["Visible"])).ToList();
                    
                    for(int r = 0; r < rollerliste.Count(); r++)
                    {
                        for (int y = 0; y < yetkiliste.Count(); y++)
                        {
                            if(rollerliste[r].ToString() == "frmMasalar" && yetkiliste[y].ToString() == "true" && r == y)
                            {
                                cu.frmMasalar = 1;
                            }
                            else
                            {
                                cu.frmMasalar = 0;
                            }
                        }
                    }

Actually if(rollerliste[r].ToString() == "frmMasalar" && yetkiliste[y].ToString() == "true" && r == y) it seems to be checking for correct data but not working.

rollerliste	yetkiliste
frmMasalar	True
frmY.netim	True

I just want to make check rollerliste if column1 is true "button.Enable = true" or false

Please use String.Equal when comparing strings.

string a = "hello"; string b = "hello";

a==b might be false, but a.Equals(b) == true
