再议ArcGIS 10.4的0x80040228错误

问题描述

今天在测试时，又遇到了0x80040228的错误。曾经也遇到过：

ArcGIS 10.4的0x80040228许可错误 - 我也是个傻瓜 - 博客园 (cnblogs.com)

主要问题是在ArcGIS10.4的环境下打开SHP工作空间时，出现0x80040228错误，错误描述如下：

System.Runtime.InteropServices.COMException (0x80040228): Exception from HRESULT: 0x80040228

at ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactoryClass.OpenFromFile(String fileName, Int32 hWnd)

官方帮助

在ESRI帮助中找到打开Shp文件的示例代码（不得不说，官方代码无论是逻辑，还注释都值得学习）。

/// <summary>
/// Get the FeatureClass from a Shapefile on disk (hard drive).
/// </summary>
/// <param name="string_ShapefileDirectory">A System.String that is the directory where the shapefile is located. Example: "C:dataUSA"</param>
/// <param name="string_ShapefileName">A System.String that is the shapefile name. Note: the shapefile extension's (.shp, .shx, .dbf, etc.) is not provided! Example: "States"</param>
/// <returns>An IFeatureClass interface. Nothing (VB.NET) or null (C#) is returned if unsuccessful.</returns>
/// <remarks></remarks>
public ESRI.ArcGIS.Geodatabase.IFeatureClass GetFeatureClassFromShapefileOnDisk(System.String string_ShapefileDirectory, System.String string_ShapefileName)
{

    System.IO.DirectoryInfo directoryInfo_check = new System.IO.DirectoryInfo(string_ShapefileDirectory);
    if (directoryInfo_check.Exists)
    {

        //We have a valid directory, proceed

        System.IO.FileInfo fileInfo_check = new System.IO.FileInfo(string_ShapefileDirectory + "\" + string_ShapefileName + ".shp");
        if (fileInfo_check.Exists)
        {

            //We have a valid shapefile, proceed

            ESRI.ArcGIS.Geodatabase.IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesFile.ShapefileWorkspaceFactoryClass();
            ESRI.ArcGIS.Geodatabase.IWorkspace workspace = workspaceFactory.OpenFromFile(string_ShapefileDirectory, 0);
            ESRI.ArcGIS.Geodatabase.IFeatureWorkspace featureWorkspace = (ESRI.ArcGIS.Geodatabase.IFeatureWorkspace)workspace; // Explict Cast
            ESRI.ArcGIS.Geodatabase.IFeatureClass featureClass = featureWorkspace.OpenFeatureClass(string_ShapefileName);

            return featureClass;
        }
        else
        {

            //Not valid shapefile
            return null;
        }

    }
    else
    {

        // Not valid directory
        return null;
    }

}

使用官方的代码仍然也现这个问题，说明不是打开代码的问题，查询错误代码0x80040228即LICENSE_NOT_INITIALIZED，还是许可的问题。

解决方案

这里不再讨论原因，只讲有效的解决方法。

方法一：改用ArcServer产品代码

将esriLicenseProductCodeAdvanced许可改为esriLicenseProductCodeArcServer，不要问为什么，经测试其他产品代码都不行。

//绑定产品
ESRI.ArcGIS.RuntimeManager.Bind(ProductCode.Desktop);

IAoInitialize aoInitialize = new AoInitializeClass();
//原初始化许可
//esriLicenseStatus licenseStatus = aoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeAdvanced);
//新初始化许可
esriLicenseStatus licenseStatus = aoInitialize.Initialize(esriLicenseProductCode. esriLicenseProductCodeArcServer);

有人说此方法无效，是因为初始化代码的位置不对。（整个软件只有第一次初始化许可有效！）

方法二：先打开其他工作空间

翻看了ESRI社区相关的讨论，shp和gdb的工作空间都是一个文件夹，有人也说了这是一个Bug，经同事测试，在打开shp的工作空间之前，先打开任意一个存在的gdb或mdb工作空间获取初始化授权后也能解决问题。测试代码如下 ：

private void button1_Click(object sender, EventArgs e)
{
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.Filter = "*.shp|*.shp";
    if (openFileDialog.ShowDialog() == DialogResult.OK)
    {
        string fileName = openFileDialog.FileName;
        string path = System.IO.Path.GetDirectoryName(fileName);
        string name = System.IO.Path.GetFileNameWithoutExtension(fileName);
                
        //先打开任意一个存在的gdb或mdb
        IWorkspaceFactory wsfgdb = new FileGDBWorkspaceFactoryClass();
        wsfgdb.OpenFromFile($"{System.Windows.Forms.Application.StartupPath}\Test.gdb", 0);

        IWorkspaceFactory wsf = new ShapefileWorkspaceFactory();
        IWorkspace pWorkspace = wsf.OpenFromFile(path, 0);
        IFeatureWorkspace pFeatureWorkspace = (IFeatureWorkspace)pWorkspace;
        IFeatureClass pFeatureClass = pFeatureWorkspace.OpenFeatureClass(name);
        MessageBox.Show(pFeatureClass.FeatureCount(null) + "");
    }
}
