需要將oracle函數轉換爲c＃代碼

我在oracle中有一個函數，我需要將它轉換爲c＃代碼請幫助或告訴我任何鏈接。需要將oracle函數轉換爲c＃代碼

我不知道PL/SQL的所有，但不是這只是[String.Split]（http://msdn.microsoft.com/en-us /library/b873y76a.aspx） – billinkc

只是爲了讓它變得簡單呃給任何人解決這個pl/sql程序的高級目的是什麼？ – Kuberchaun

如果你提供這個函數的幾個樣本輸入/輸出並描述應該做什麼而不是隻是拋出代碼並尋求幫助，那對你來說會非常好。並非所有人都知道或掌握了Oracle，但許多人都可以編寫C＃。 – Icarus

我不明白你爲什麼不能自己轉換它？問題是什麼？你甚至會得到一個評論，描述該功能在做什麼。

做這樣的事情：

轉換方法簽名和所有本地變量C＃的。
查詢看到INSTR的文件，如果使用基於零的索引爲string.IndexOf
做直轉換通過一次
測試功能
看着一個行以重命名所有的變量有C＃的名字
重構利用C＃
