GridView绑定数据时候怎么过滤掉特殊符号，英文字母

DataList_brand.DataSource = (from c in db.computer_brand_table where c.distinguish.ToString() == d_id.ToString() select c).Take(18);
DataList_brand.DataBind();

怎么过滤掉其中的字母和特殊符号，只留汉字

var data = (from c in db.computer_brand_table where c.distinguish.ToString() == d_id.ToString() select c).Take(18); data = data.Select(new XXX { A = Filter(c.A), B = Filter(c.B), ... });

绑定之前先用正则将非汉字字符replace为""
