DataGridView::RowFilter特殊文字のエスケープ

DataColumn.Expression プロパティ (System.Data)に記されているのですが、分かりづらいのでまとめてみました。
（実際のコードでしまします）

class EscapePair
{
 public EscapePair(char specialChar, string prefix, string surfix)
 {
     SpecialChar = specialChar;
     Prefix = prefix;
     Surfix = surfix;
 }

 public string Surfix;
}

// ~ ( ) # \ / = > < + - * % & | ^ ' " [ ]
private EscapePair[] EscapePairs = new EscapePair[]
 {
     new EscapePair('~', "[", "]"),
     new EscapePair('(', "[", "]"),
     new EscapePair(')', "[", "]"),

 };
