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

int main()

注解

将转换 value 的所有元素。All the elements of value are converted. @No__t-0 方法返回的十六进制字符串的顺序取决于计算机体系结构是小字节序还是大字节序。The order of hexadecimal strings returned by the ToString method depends on whether the computer architecture is little-endian or big-endian.

ToString(Byte[], Int32) ToString(Byte[], Int32) ToString(Byte[], Int32) ToString(Byte[], Int32)

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。Converts the numeric value of each element of a specified subarray of bytes to its equivalent hexadecimal string representation.

public:
 static System::String ^ ToString(cli::array <System::Byte> ^ value, int startIndex);
public static string ToString (byte[] value, int startIndex);
static member ToString : byte[] * int -> string
Public Shared Function ToString (value As Byte(), startIndex As Integer) As String

参数

value
Byte[]

字节数组。An array of bytes.

startIndex
Int32 Int32 Int32 Int32

value 内的起始位置。The starting position within value.

返回

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”。A string of hexadecimal pairs separated by hyphens, where each pair represents the corresponding element in a subarray of value; for example, "7F-2C-4A-00".

异常

startIndex 小于零或大于 value 减 1 的长度。startIndex is less than zero or greater than the length of value minus 1.

示例

下面的代码示例将 @no__t 0 数组的部分从指定的 startIndex 开始转换为具有 ToString 方法的 StringThe following code example converts the part of a Byte array starting at the specified startIndex to a String with the ToString method.

注解

转换数组位置 startIndex 到数组末尾之间的元素。The elements from array position startIndex to the end of the array are converted. @No__t-0 方法返回的十六进制字符串的顺序取决于计算机体系结构是小字节序还是大字节序。The order of hexadecimal strings returned by the ToString method depends on whether the computer architecture is little-endian or big-endian.

ToString(Byte[], Int32, Int32) ToString(Byte[], Int32, Int32) ToString(Byte[], Int32, Int32) ToString(Byte[], Int32, Int32)

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。Converts the numeric value of each element of a specified subarray of bytes to its equivalent hexadecimal string representation.

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[]

字节数组。An array of bytes.

startIndex
Int32 Int32 Int32 Int32

value 内的起始位置。The starting position within value.

length
Int32 Int32 Int32 Int32

要转换的 value 中的数组元素数。The number of array elements in value to convert.

返回

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”。A string of hexadecimal pairs separated by hyphens, where each pair represents the corresponding element in a subarray of value; for example, "7F-2C-4A-00".

异常

startIndexlength 小于零。startIndex or length is less than zero.

-or- startIndex 大于零且大于等于 value 的长度。startIndex is greater than zero and is greater than or equal to the length of value.

startIndexlength 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。The combination of startIndex and length does not specify a position within value; that is, the startIndex parameter is greater than the length of value minus the length parameter.

示例

下面的示例使用 ToString 方法将字节数组的部分(从指定的 @no__t-@no__t 1 开始)转换为字符串。The following example uses the ToString method to convert part of a byte array, starting at the specified startIndex and with the specified length, to a string.

注解

转换数组位置 @no__t length 元素。The length elements from array position startIndex are converted. 如果 @no__t 0 等于零,则该方法返回 String.EmptyIf length equals zero, the method returns String.Empty.

@No__t-0 方法返回的十六进制字符串的顺序取决于计算机体系结构是小字节序还是大字节序。The order of hexadecimal strings returned by the ToString method depends on whether the computer architecture is little-endian or big-endian.
