範例

下列程式碼範例會將 URI，然後將任何加號字元 ( "+" ) 轉換為空格。The following code example unescapes a URI, and then converts any plus characters ("+") into spaces.

String DataString = Uri.UnescapeDataString(".NET+Framework");
Console.WriteLine("Unescaped string: {0}", DataString);

String PlusString = DataString.Replace('+',' ');
Console.WriteLine("plus to space string: {0}", PlusString);

備註

您應該小心使用這個方法。You should use this method with care. 未逸出先前未經過非工作字串的字串可能會導致不明確和錯誤。Unescaping a string that has been previously unescaped can lead to ambiguities and errors.

許多網頁瀏覽器會將 Uri 內的空格換成加號 ( "+" ) 字元;但是，System.uri.unescapedatastring 方法不會將加號字元轉換成空格，因為在所有的 URI 配置中，這種行為不是標準的。Many Web browsers escape spaces inside of URIs into plus ("+") characters; however, the UnescapeDataString method does not convert plus characters into spaces because this behavior is not standard across all URI schemes.
