修復macOS ARM上的IronPdfEngine Docker連線失敗

Updated: 2026年6月10日

當在macOS ARM裝置（Apple Silicon）上透過Docker將.NET應用程式連接到IronPdfEngine時，應用程式拋出異常：

Unhandled exception. System.IO.FileNotFoundException: Error loading native library.
Not found in any of the possible locations

Unhandled exception. System.IO.FileNotFoundException: Error loading native library.

IronPdfConnectionType.Docker 使用了較舊的gRPC實現，不支持ARM架構。在macOS ARM（Apple Silicon）上，即使強制Docker映像以--platform linux/amd64運行，.NET客戶端也無法載入所需的原生gRPC二進位。 Windows和Linux x64平台不受影響。

解決方案

在連線配置中將IronPdfConnectionType.RemoteServer。 RemoteServer 使用了較新的gRPC實現，支持ARM：

using IronPdf;

var config = new IronPdfConnectionConfiguration
{
    ConnectionType = IronPdfConnectionType.RemoteServer,
    Host = "http://127.0.0.1",
    Port = 33350
};

IronPdf.Installation.ConnectToIronPdfHost(config);

IronPdf.License.LicenseKey = Environment.GetEnvironmentVariable("IRONPDF_LICENSE_KEY");

var renderer = new ChromePdfRenderer();
var pdf = await renderer.RenderHtmlAsPdfAsync("<h1>Hello from IronPdfEngine</h1>");
pdf.SaveAs("output.pdf");

using IronPdf;

var config = new IronPdfConnectionConfiguration
{
    ConnectionType = IronPdfConnectionType.RemoteServer,
    Host = "http://127.0.0.1",
    Port = 33350
};

IronPdf.Installation.ConnectToIronPdfHost(config);

IronPdf.License.LicenseKey = Environment.GetEnvironmentVariable("IRONPDF_LICENSE_KEY");

var renderer = new ChromePdfRenderer();
var pdf = await renderer.RenderHtmlAsPdfAsync("<h1>Hello from IronPdfEngine</h1>");
pdf.SaveAs("output.pdf");

Imports IronPdf

Dim config As New IronPdfConnectionConfiguration With {
    .ConnectionType = IronPdfConnectionType.RemoteServer,
    .Host = "http://127.0.0.1",
    .Port = 33350
}

IronPdf.Installation.ConnectToIronPdfHost(config)

IronPdf.License.LicenseKey = Environment.GetEnvironmentVariable("IRONPDF_LICENSE_KEY")

Dim renderer As New ChromePdfRenderer()
Dim pdf = Await renderer.RenderHtmlAsPdfAsync("<h1>Hello from IronPdfEngine</h1>")
pdf.SaveAs("output.pdf")

Imports IronPdf

Dim config As New IronPdfConnectionConfiguration With {
    .ConnectionType = IronPdfConnectionType.RemoteServer,
    .Host = "http://127.0.0.1",
    .Port = 33350
}

IronPdf.Installation.ConnectToIronPdfHost(config)

IronPdf.License.LicenseKey = Environment.GetEnvironmentVariable("IRONPDF_LICENSE_KEY")

Dim renderer As New ChromePdfRenderer()
Dim pdf = Await renderer.RenderHtmlAsPdfAsync("<h1>Hello from IronPdfEngine</h1>")
pdf.SaveAs("output.pdf")
