怎样实例化strSql
public DataSet GetList(int FTypeID)
{
StringBuilder strSql = new StringBuilder();
strSql.Append("select * ");
strSql.Append(" FROM TProductsType where FTypeID=@FTypeID");
return DBHelper.Query(strSql.ToString());
}
总是说没有声明标量变量@FTypeID
怎样把strSql实例化

[解决办法]
改改
strSql.Append( string.Format(" FROM TProductsType where FTypeID={0}",FTypeID));
