將字符串數組轉換爲字節數組並返回

Question

我想將字符串數組轉換爲字節數組。我想使用Encoding.Default.GetBytes()，但它只接受String和Char()。這是代碼

Dim aStringArray(2) As String 

aStringArray(0) = "FileName" 
aStringArray(1) = "FileSize" 

Dim stringArrayBytes() As Byte = Encoding.Default.GetBytes(aStringArray) `this is wrong 

Answer 1

如果你想在陣列組合成一個單一的字節數組試試這個

Dim aStringArray(1) As String 

    aStringArray(0) = "FileName" 
    aStringArray(1) = "FileSize" 

    Dim stringArrayBytes As New List(Of Byte) 
    For Each s As String In aStringArray 
     stringArrayBytes.AddRange(System.Text.Encoding.Default.GetBytes(s)) 
    Next 

    Dim bytarray() As Byte = stringArrayBytes.ToArray 

Answer 2

在這裏，小競標不同的方法，根據您的例子:)

Dim aStringArray(2) As String 

aStringArray(0) = "FileName" 
aStringArray(1) = "FileSize" 

Dim allStrngItems As String = String.Join(String.Empty, aStringArray) 
Dim allBytes As Byte() = Encoding.Default.GetBytes(allStrngItems)
