How to use indexOf() case insensitive


You can Use Overloaded Method

IndexOf("punctuation",
StringComparison.OrdinalIgnoreCase);

Eg.

List<string> fnColArr = new
List<string>() 
{ "Punctuation", "period", "Space", "and", "yes"
};

            foreach (string item in fnColArr)
            {
                if (item.IndexOf("puNctuation",
StringComparison.OrdinalIgnoreCase) >= 0)
                {
                    Console.WriteLine("match");

                }
            }

Case-insensitive "contains" in Linq
the easy way is to use ToLower() method var lists = rec.Where(p => p.Name.ToLower().Contains(records.Name.ToLower())).ToList(); a better solution (based on this post: Case insensitive 'Contains(string)') var lists = rec.Where(p => CultureInfo.CurrentCulture.CompareInfo.IndexOf (p.Name, records.Name, CompareOptions.IgnoreCase) >= 0).ToList();

Case-insensitive primary key of type nvarchar where ß != ss
The closest I can get to a workaround is using an indexed view to add a unique constraint on UPPER(ID) to stop primary key violation that is not picked up by the binary collation used on the actual primary key, e.g. CREATE TABLE CollationTest ( ID NVARCHAR(50) COLLATE Latin1_General_BIN NOT NULL, CONSTRAINT PK_CollationTest_ID PRIMARY KEY (ID) ); GO CREATE VIEW dbo.CollationTestConst
