Here is a minor variant of Brian's answer that someone else may find useful. Takes a List of keys and drops it into the parameter list.

//keyList is a List
System.Data.SqlClient.SqlCommand command = new System.Data.SqlClient.SqlCommand();
string sql = "SELECT fieldList FROM dbo.tableName WHERE keyField in (";
int i = 1;
foreach (string key in keyList) {
    sql = sql + "@key" + i + ",";
    command.Parameters.AddWithValue("@key" + i, key);
    i++;
}
sql = sql.TrimEnd(',') + ")";
