X-UA-Compatible設置IE兼容模式

[HTML]X-UA-Compatible設置IE兼容模式

強制瀏覽器呈現為特定的版本的標準。它不支持IE7及以下：
<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7"/>

如果用分號分開，它設置為不同版本的兼容級別，IE7、IE9。它允許不同層次的向後兼容性：
<meta http-equiv="X-UA-Compatible" content="IE=7; IE-9"/>

只選擇其中一個選項：
<meta http-equiv="X-UA-Compatible" content="IE=9">
<meta http-equiv="X-UA-Compatible" content="IE=8"/>
<meta http-equiv="X-UA-Compatible" content="IE=7">
<meta http-equiv="X-UA-Compatible" content="IE=5">

允許更容易的測試和維護。雖然通常比較有用的版本，這是使用模擬：
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9"/>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8"/>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7">

什麼版本IE 就用什麼版本的標準模式：
<meta http-equiv="X-UA-Compatible" content="IE=edge">

使用以下代碼強制IE 使用Chrome Frame：
<meta http-equiv="X-UA-Compatible" content="chrome=1">

最佳的兼容模式方案，結合考慮以上兩種：
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

指定文件兼容性模式，在網頁中使用meta元素放入X-UA-Compatible  http-equiv  標頭。以下是指定為Emulate IE7 mode兼容性之範例：
< html >
< head >
  <!--  Mimic Internet Explorer 7  -->
  < meta  http-equiv ="X-UA-Compatible"  content ="IE=EmulateIE7"  />
  < title > My Web Page </ title >
< / head >
< body >
</ body >
</ html >

設定網站服務器以指定預設兼容性模式：
<?xml version="1.0" encoding="utf-8"?>
<configuration>
   <system.webServer>
      <httpProtocol>
         <customHeaders>
            <clear />
            <add name="X-UA-Compatible" value="IE=EmulateIE7" />
         </customHeaders>
      </httpProtocol>
   </system.webServer>
</configuration>

C# ASCII字碼轉換應用

C# ASCII字碼轉換應用

如何將英文字母大寫”A”轉換為”65”與如何將”65”轉換為英文字母大寫的”A”。
下列範例中RetAsciiCode將大寫”A”轉換成”65”後return給呼叫RetAsciiCode的原程序變數，另外RetAsciiChar帶入一個數字(asciiCode)例如”65”，轉換成大寫”A”並將結果return給呼叫的原程序變數。

C#:

    int intAsciiCode = Int32.Parse(RetAsciiCode(“A”)); //回傳數字65
    string strAsciiChar = RetAsciiChar(65);  //回傳大寫A

    public int RetAsciiCode(string MyString)

        if (MyString.Length == 0)
            return 0;
        else if (MyString.Length > 1)
