问题描述

我正在将十六进制颜色值转换为颜色名称.

转换时，我遇到这样的错误:"ffffff80对于Int32而言不是有效值."

以下是我的代码

Hi,

I am converting hex color value into color name.

While converting, I am facing the error like this "ffffff80 is not a valid value for Int32."

Below is my code

Dim xCol As String = clspfjbs02.colrnameobj
                   Dim k As Color
                   k = System.Drawing.ColorTranslator.FromHtml(xCol)

推荐答案

Dim xCol As String = "#" & clspfjbs02.colrnameobj
Dim k As Color
k = System.Drawing.ColorTranslator.FromHtml(xCol)

Dim xCol As Int32
Dim k As Color
xCol = Int32.Parse(clspfjbs02.colrnameob, HexNumber)
k = System.Drawing.ColorTranslator.FromHtml(xCol)

k = System.Drawing.ColorTranslator.FromWin32(Integer.Parse("ffffff80", System.Globalization.NumberStyles.HexNumber))
