IronOCR 中 SEHException 和 AVX 支持故障排除

Updated: 2026年6月29日

未处理的异常：System.Runtime.InteropServices.SEHException

使用缺乏 AVX 支持的旧款 Xeon、Celeron、Pentium 或 Atom 处理器的机器经常会遇到这个问题。

对非AVX处理器的支持已添加在IronOCR版本2022.8.7804中，因此请升级到更高版本。

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

// Example: Checking AVX support programmatically in C#
using System;

class ProcessorFeatures
{
    // Main method to check AVX support
    static void Main()
    {
        // Check if the machine's processor supports AVX
        if (IsAvxSupported())
        {
            Console.WriteLine("AVX is supported.");
        }
        else
        {
            Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.");
        }
    }

    // Function to determine if AVX is supported
    static bool IsAvxSupported()
    {
        return System.Runtime.Intrinsics.X86.Avx.IsSupported;
    }
}

' Example: Checking AVX support programmatically in C#
Imports System

Friend Class ProcessorFeatures
	' Main method to check AVX support
	Shared Sub Main()
		' Check if the machine's processor supports AVX
		If IsAvxSupported() Then
			Console.WriteLine("AVX is supported.")
		Else
			Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.")
		End If
	End Sub

	' Function to determine if AVX is supported
	Private Shared Function IsAvxSupported() As Boolean
		Return System.Runtime.Intrinsics.X86.Avx.IsSupported
	End Function
End Class

' Example: Checking AVX support programmatically in C#
Imports System

Friend Class ProcessorFeatures
	' Main method to check AVX support
	Shared Sub Main()
		' Check if the machine's processor supports AVX
		If IsAvxSupported() Then
			Console.WriteLine("AVX is supported.")
		Else
			Console.WriteLine("AVX is not supported. Consider updating IronOcr to the latest version that supports non-AVX processors.")
		End If
	End Sub

	' Function to determine if AVX is supported
	Private Shared Function IsAvxSupported() As Boolean
		Return System.Runtime.Intrinsics.X86.Avx.IsSupported
	End Function
End Class

在此示例代码中，我们使用System.Runtime.Intrinsics.X86.Avx.IsSupported属性来确定处理器是否支持AVX指令。如果不支持AVX，建议确保您使用的IronOCR版本包含对非AVX处理器的支持。
