sql - c# - using % as a text symbol(percent) -

i'm searching in datatable

        datarow[] found = table.select(f_sep);

//table - datatable, f_sep - string query looks like: f_text '%some_word%'

in query need use % percent(to find percent values). if in query write 5% return results 5 , other symbols after it, tried replace %:

string stt = textbox.text.replace("%", "'%'");

i error - can't use operator mod

replace("%", "\"%\"");

i error using operator.

how can replace % ?

you need escape % sign,

use brackets. 75%

where mycol '%75[%]%'
