Convert.ToString的问题

[qjsbha]

Convert.ToString(charTemp, 16);chartemp是一个特殊字符。这是什么意思？转换后加上%是多少了？

[wfcfan]

变量吧。。？

[michaelnami]

%是转义的意思 d%就是数字

[simen_frankly]

看不懂啊~能否详细些~~~~~

[xzq686]

转换成16进制的串..
Convert.ToString('a',10) = "97"
上面的是转成10进制

加上 "%"就是"97%"

ToString 方法 (Int32, Int32)
.NET Framework 类库
Convert.ToString 方法 (Int32, Int32)
将 32 位有符号整数的值以指定的基数转换为它的等效 String 表示形式。

命名空间:System
程序集:mscorlib（在 mscorlib.dll 中）

语法
Visual Basic（声明）
Public Shared Function ToString ( _
value As Integer, _
toBase As Integer _
) As StringVisual Basic（用法）
Dim value As Integer
Dim toBase As Integer
Dim returnValue As String

returnValue = Convert.ToString(value, toBase)C#
public static string ToString (
int value,
int toBase
)C++
public:
static String^ ToString (
int value,
int toBase
)J#
public static String ToString (
int value,
int toBase
)JScript
public static function ToString (
value : int,
toBase : int
) : String

参数
value
32 位的有符号整数。

toBase
返回值的基数，必须是 2、8、10 或 16。



返回值
以 toBase 为基数的 value 的 String 表示形式。
异常
异常类型 条件
ArgumentException
toBase 不是 2、8、10 或 16。


示例
下面的代码示例使用 ToString 方法，以该方法支持的基数将几个 32 位整数转换为 String。
