示例

下面的代码示例使用 ByteToString 方法将String数组转换为对象。

   Console::WriteLine( name );
   Console::WriteLine( underLine->Substring( 0, Math::Min( name->Length, underLine->Length ) ) );
   Console::WriteLine( BitConverter::ToString( bytes ) );
   Console::WriteLine();
}

int main()
{
   array<unsigned char>^arrayOne = {0,1,2,4,8,16,32,64,128,255};
   array<unsigned char>^arrayTwo = {32,0,0,42,0,65,0,125,0,197,0,168,3,41,4,172,32};

注解

将转换从数组位置 startIndex 到数组末尾的元素。

适用于

ToString(Byte[], Int32, Int32)

Source:: BitConverter.cs

Source:: BitConverter.cs

Source:: BitConverter.cs

将指定的字节子数组的每个元素的数值转换为它的等效十六进制字符串表示形式。

public:
 static System::String ^ ToString(cli::array <System::Byte> ^ value, int startIndex, int length);

public static string ToString (byte[] value, int startIndex, int length);

static member ToString : byte[] * int * int -> string

Public Shared Function ToString (value As Byte(), startIndex As Integer, length As Integer) As String

参数

value: Byte[]

包含要转换的字节的字节数组。

startIndex: Int32

value 内的起始位置。

length: Int32

要转换的 value 中的数组元素数。

String

由以连字符分隔的十六进制对构成的字符串，其中每一对表示 value 的子数组中对应的元素；例如“7F-2C-4A”。

例外

ArgumentNullException

value 为 null。

ArgumentOutOfRangeException

startIndex 或 length 小于零。

- 或 -

startIndex 大于零且大于等于 value 的长度。

ArgumentException

startIndex 和 length 的组合不指定 value 中的位置；也就是说，startIndex 参数大于 value 的长度减去 length 参数。

示例

以下示例使用 ToString 方法将字节数组的一部分（从指定的 startIndex 和指定的 length）转换为字符串。
