Replacing singlequotes with double quotes

Hi,
 i have an SQL insert statement which inserts a string into the database. However my string contains single quotes. Iam trying to replace the single quotes with double quotes for proper insertion into sql server.

 firstchars= firstchars.Replace("'",  " " " ).Trim();

insert into table values(firstchars);

Iam getting an error as new line constant expected.

Can anyone tell me what the correct code is??

Any furthur comments and suggestions are welcome.

Thanks in advance.

I think you need this as your command string:

string sSqlCommand = "insert into table values('" + firstchars + "')";

Ok, third times a charm:
Place a backslash before the double quote
firstchars= firstchars.Replace("'",  "\"" ).Trim();

Hi sendmeblah ,

does the code firstchars= firstchars.Replace("'",  "\"" ).Trim(); replaces single quotes with \"
or with only "

Thanks.

The \" is an escape character that means place a literal double quote.  Try this:

firstchar = "This string ' has a quote";
firstchars= firstchars.Replace("'",  "\"" ).Trim();

Console.WriteLine(firstchars);

and in the Output window you will see:
This string " has a quote
