How do i escape mysql strings in C# for use with LIKE

I want to find a word in my list of tags. They can be at the beginning, end or middle so i tried writing.

Where name like "%@0%"

That didnt work so i tried

@"LIKE ""%" + MySql.Data.MySqlClient.MySqlHelper.EscapeString(q) +@"%"

I thought that worked so i tried searching %. The results showed up all my tags, i expected only tags with % in them (so that would be none ATM).

How do i escape strings properly? and use it to search the middle of text?

-edit-

The solution开发者_如何学JAVA is the below. I ran it against a few test and it passed them all. The query is

... where n.name LIKE CONCAT("%",  @some_name , "%") ...;

then in code

cmd.Parameters.AddWithValue("@some_name", val.Replace("\\", "\\\\").Replace("_", "\\_").Replace("%", "\\%")));

You also need to escape % and _ characters in the string, since those are special wildcards used by the LIKE operator:

@"LIKE ""%" +
    MySql.Data.MySqlClient.MySqlHelper.EscapeString(q)
        .Replace("_", "\\_").Replace("%", "\\%") +
    @"%"

You might consider wrapping this in a static method for reusability.
