Is there a way to get the index of a item within a List with case insensitive search?
List<string> sl = new List<string>() { "a","b","c"};
int result = sl.IndexOf("B"); // should be 1 instead of -1
387
The indexOf() method returns the index number where the target string is first found or -1 if the target is not found. Like equals(), the indexOf() method is case-sensitive, so uppercase and lowercase chars are considered to be different.
The indexOf() method returns the position of the first occurrence of a value in a string. The indexOf() method returns -1 if the value is not found. The indexOf() method is case sensitive.
IndexOf Method is by default case sensitive. But we can make it case insensitive if we use one of the overloads: IndexOf(String, StringComparison).
Try this : So there is no direct way to use IndexOf with String Comparison option for LIST, to achieve desire result you need to use Lambda expression.
int result = sl.FindIndex(x => x.Equals("B",StringComparison.OrdinalIgnoreCase));
