Why can't I define a case-insensitve Dictionary in C#?
- by Edward Tanguay
This WPF code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace TestDict28342343
{
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
Dictionary<string, string> variableNamesAndValues =
new Dictionary<string, string>(StringComparison.InvariantCultureIgnoreCase);
}
}
}
gives me the error:
The best overloaded method match for
'System.Collections.Generic.Dictionary.Dictionary(System.Collections.Generic.IDictionary)'
has some invalid arguments
Yet I find this code example everywhere such as here and here.
How can I define a Dictionary whose keys are case-insensitve?
