關於DataTable 裡面用 /轉義符拼接的問題

//這種寫法表面上是正確，實現上在執行時呼叫Select方法實行查詢會報錯 
string str = resetstrWhere + "\"" + "," + "\"" + dataQuery.DefaultOrderByClause;
 table = table.Select(str).CopyToDataTable();

//這種寫法表面上是正確，實現上在執行時呼叫Select方法實行查詢會報錯
string str = string.Format("{0}\",\"{1}", resetstrWhere, dataQuery.DefaultOrderByClause);

table 
 
= table.Select(str).CopyToDataTable();

//這種方法是正確的。
DataTable table =new DataTable();

table = table.Select(string.Format("{0}", resetstrWhere), string.Format("{0}", Tool.sortName + strtype)).CopyToDataTable();

DataTable 使用Select方法

Select();

Select("id>='3' and name='3--hello'");//支援and

Select("id>='3' or id='1'");//支援or

Select("name like '%hello%'");//支援like   

 Select("id>5","id desc");

Select("id>5", "id desc",DataViewRowState.Added);
