How can I send Hebrew text to SQL Server from a C# ASP.NET parameter?

Question

When words_array[i] is Hebrew text, the database shows '?????' in place of the word.

myCommand.CommandText = "INSERT INTO MyTable(word) VALUES (@word);
myCommand.Parameters.Add(new SqlParameter("@word", SqlDbType.Varchar, 50));
command.Parameters["@word"].Value = words_array[i];

I tried below, but got an error :

Incorrect syntax near 'N'

My attempt:

myCommand.CommandText = "INSERT INTO MyTable(word) VALUES (N'@word'N);

I tried this, too - problem: placed the text '@word' in place of the Hebrew word.

myCommand.CommandText = "INSERT INTO MyTable(word) VALUES (N'@word');

Answer 1

Change SqlDbType.VarChar with SqlDbType.NVarChar . There's no need to prefix strings when using parameterized queries.

The line :

myCommand.Parameters.Add(new SqlParameter("@word",SqlDbType.VarChar,50));

Says that the parameter's type is a string using a single-byte codepage instead of a Unicode string. Strings in .NET are Unicode but this line tells the driver to convert the value to a single-byte encoding using the codepage specified by the thread's CurrentCultureInfo .

It should be

myCommand.Parameters.Add(new SqlParameter("@word",SqlDbType.NVarChar,50));
