修复macOS ARM上IronPdfEngine Docker连接失败

Updated: 2026年6月10日

在macOS ARM设备（Apple Silicon）上通过Docker连接.NET应用程序到IronPdfEngine时，应用程序会引发：

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

IronPdfConnectionType.Docker 使用较旧的gRPC实现，不支持ARM架构。在macOS ARM (Apple Silicon)上，即使强制Docker镜像以--platform linux/amd64方式运行，.NET客户端也无法加载所需的本地gRPC二进制文件。 Windows和Linux x64平台不受影响。

解决方案

在连接配置中，用IronPdfConnectionType.Docker。 RemoteServer 使用与ARM兼容的较新的gRPC实现：

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")
