How To Pass Paremeter To A Select Statement?

I have this.

string strConn = ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

string strQuery = "SELECT * FROM enews WHERE ((name_nws LIKE %'" + strSearch + "'%)";

SqlDataAdapter newsResultAdapter = new SqlDataAdapter(strQuery, strConn);

//create a new dataset
DataSet dsNewsSearch = new DataSet();

//populate the dataset with the "board_mtg_date" table from the database
newsResultAdapter.Fill(dsNewsSearch, "enews");

//go through each rows in the dataset
foreach (DataRow dr in dsNewsSearch.Tables[0].Rows)
{
int newsID = Convert.ToInt16(dr["id_nws"]);

} I'm trying to pass a value to the Select statement with the variable "strSearch". It kept giving me error on this section.

The error is:

[SqlException (0x80131904): Line 1: Incorrect syntax near 'Challenge'.]"Challenge" is the text I passed it in.
