IronBarcode - 替代 System.Drawing.Common

View the article in English

Iron Software 有一個名為 IronDrawing 的開源替代方案，用於替代 System.Drawing.Common。欲了解更多關於IronDrawing的資訊，點擊這裡.

從 .NET 6 開始，System.Drawing.Common 僅適用於 Windows.

在非 Windows 作業系統上，除非您設置運行時配置開關，否則會拋出 TypeInitializationException 異常，內部異常為 PlatformNotSupportedException。
在 .NET 6 中，當參考代碼為非 Windows 操作系統編譯時，平台分析器會發出編譯時警告。此外，除非您設置了配置選項，否則將拋出以下運行時異常：

System.TypeInitializationException : The type initializer for 'Gdip' threw an exception.
          ---- System.PlatformNotSupportedException : System.Drawing.Common is not supported on non-Windows platforms. See https://aka.ms/systemdrawingnonwindows for more information.

Stack Trace:

          /_/src/libraries/System.Drawing.Common/src/System/Drawing/Gdiplus.cs(27,0): at System.Drawing.SafeNativeMethods.Gdip..cctor()

臨時解決方案：透過在 runtimeconfig.json 文件中將 System.Drawing.EnableUnixSupport 運行時配置開關設置為 true 來啟用對非 Windows 平台的支持：

{
         "runtimeOptions": {
            "configProperties": {
               "System.Drawing.EnableUnixSupport": true
            }
         }
      }

此解決方案是 Microsoft 目前在 .NET 6 中對 System.Drawing 支援的解決方案：
