如何将ConsoleColor转换为Color类型？

我需要这个来创建这个方法的重载，它应该返回一个颜色而不是Consolecolor：

    ''' <summary>
    ''' Generates a random ConsoleColor color.
    ''' </summary>
    ''' <returns>ConsoleColor.</returns>
    Public Shared Function [ConsoleColor]() As ConsoleColor

        Dim Rand As New Random
        Return [Enum].Parse(GetType(ConsoleColor), 
                            Rand.Next(0, 15))

    End Function

这是我尝试过的，但有时返回的颜色为空，因为ConsoleColor名称未知：

    ''' <summary>
    ''' Generates a random QB color.
    ''' </summary>
    ''' <returns>Color.</returns>
    Public Shared Function QB() As Color

        Dim Rand As New Random
        Return Color.FromName([Enum].Parse(GetType(ConsoleColor), 
                              Rand.Next(0, 15)).ToString)

    End Function

PS：我想避免使用旧的VB6方法（QBColor函数）。

我今天自己有这个问题，并且不能同意目前的答案。

我最终检查了所有值，发现这些值非常不同，我不知道为什么人们会建议按名称转换＆＃39;。

## Name         Actual      Drawing.Color of same name
 0 Black        #000000     #000000
 1 DarkBlue     #000080     #00008B
 2 DarkGreen    #008000     #006400
 3 DarkCyan     #008080     #008B8B
 4 DarkRed      #800000     #8B0000
 5 DarkMagenta  #800080     #8B008B
 6 DarkYellow   #808000     #000000
 7 Gray         #C0C0C0     #808080
 8 DarkGray     #808080     #A9A9A9
 9 Blue         #0000FF     #0000FF
10 Green        #00FF00     #008000
11 Cyan         #00FFFF     #00FFFF
12 Red          #FF0000     #FF0000
13 Magenta      #FF00FF     #FF00FF
14 Yellow       #FFFF00     #FFFF00
15 White        #FFFFFF     #FFFFFF

怎么样，

Module ColorExtension

    <Extension()>
    Public Function DrawingColor(ByVal color As ConsoleColor) As Color
        Select color
            Case ConsoleColor.Black
                Return Color.Black

            Case ConsoleColor.Blue
                Return Color.Blue

            Case ConsoleColor.Cyan
                Return Color.Cyan

            Case ConsoleColor.DarkBlue
                Return ColorTranslator.FromHtml("#000080")

            Case ConsoleColor.DarkGray
                Return ColorTranslator.FromHtml("#808080")

            Case ConsoleColor.DarkGreen
                Return ColorTranslator.FromHtml("#008000")

            Case ConsoleColor.DarkMagenta
                Return ColorTranslator.FromHtml("#800080")

            Case ConsoleColor.DarkRed
                Return ColorTranslator.FromHtml("#800000")

            Case ConsoleColor.DarkYellow
                Return ColorTranslator.FromHtml("#808000")

            Case ConsoleColor.Gray
                Return ColorTranslator.FromHtml("#C0C0C0")

            Case ConsoleColor.Green
                Return ColorTranslator.FromHtml("#00FF00")

            Case ConsoleColor.Magenta
                Return Color.Magenta

            Case ConsoleColor.Red
                Return Color.Red

            Case ConsoleColor.White
                Return Color.White

            Case Else
                Return Color.Yellow
        End Select
    End Function
End Module

允许，

Dim result As Drawing.Color = ConsoleColor.Red.DrawingColor()

只是改编了@Jodrell解决方案

    ''' <summary>
    ''' Generates a random QB color.
    ''' </summary>
    ''' <returns>Color.</returns>
    Public Shared Function QB() As Color

        Dim Rand As New Random
        Dim c As Color = Color.FromName([Enum].Parse(GetType(ConsoleColor),
                                                     Rand.Next(0, 15)).ToString)

        Select Case c.IsKnownColor

            ' Fix for the 'Consolecolor.DarkYellow' value which doesn't have color information.
            Case False
                Return Color.FromArgb(255, 128, 128, 0)

            Case Else
                Return c

        End Select

    End Function
