注釈

配列の位置から要素startIndex配列の末尾に変換されます。The elements from array position startIndex to the end of the array are converted. によって返される文字列の 16 進数の順序、ToStringメソッドは、コンピューターのアーキテクチャがリトル エンディアンまたはビッグ エンディアンがかどうかによって異なります。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)

指定されたバイト サブ配列の各要素の数値をそれと等価な 16 進数文字列形式に変換します。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

パラメーター

value
Byte[]

バイト配列。An array of bytes.

startIndex
Int32 Int32 Int32 Int32

value 内の開始位置。The starting position within value.

length
Int32 Int32 Int32 Int32

変換する value の配列要素の数。The number of array elements in value to convert.

戻り値

value のサブ配列内の対応する要素を表す 16 進値がハイフンで区切られている文字列 ("7F-2C-4A-00" など)。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".

例外

startIndex または length が 0 未満です。startIndex or length is less than zero.

または-or- startIndex が 0 より大きく、value の長さ以上になっています。startIndex is greater than zero and is greater than or equal to the length of value.

startIndexlength の組み合わせが、value 内の位置を指定していません。つまり、startIndex パラメーターが、value の長さから length パラメーターの値を減算した値より大きくなっています。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.

次の例では、ToStringに、指定したバイト配列の一部を変換するメソッドstartIndexと指定したlength文字列にします。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.

注釈

length要素配列位置からstartIndex変換されます。The length elements from array position startIndex are converted. 場合lengthが 0 を返しますString.Emptyします。If length equals zero, the method returns String.Empty.

によって返される文字列の 16 進数の順序、ToStringメソッドは、コンピューターのアーキテクチャがリトル エンディアンまたはビッグ エンディアンがかどうかによって異なります。The order of hexadecimal strings returned by the ToString method depends on whether the computer architecture is little-endian or big-endian.
