Question

我在ASP .NET应用程序中使用Open Office API从* .doc文件中读取文本内容。

public static bool getTextV2(string siteURL, string[] search)
{
    //Create a new ServiceManager Type object
    Type tServiceManager = Type.GetTypeFromProgID("com.sun.star.ServiceManager", true);
    //Create a new ServiceManager Com object using our
    //ServiceManager type object
    object oServiceManager = System.Activator.CreateInstance(tServiceManager);
    //Create our Desktop Com object
    object oDesktop = Invoke(oServiceManager, "createinstance",
    BindingFlags.InvokeMethod,
    "com.sun.star.frame.Desktop");
    //Create an array for our load parameter
    Object[] arg = new Object[4];
    arg[0] = siteURL;
    arg[1] = "_blank";
    arg[2] = 0;
    arg[3] = new Object[] { };
    //Create our new blank document
    object oComponent = Invoke(oDesktop,
    "loadComponentFromUrl",
    BindingFlags.InvokeMethod,
    arg
    );
    //Create an empty array for the getText method
    arg = new Object[0];
    //Get our Text Com object
    Object oText = Invoke(oComponent,
    "getText",
    BindingFlags.InvokeMethod,
    arg
    );
    Object Text = Invoke(oText,
    "getString",
    BindingFlags.InvokeMethod,
    arg
    );
    string content = Text.ToString();
    content = content.ToLower();
    bool flag = true;
    foreach (string current in search)
    {
        if (!content.Contains(current)) flag = false;
    }
    arg = new Object[0];
    Invoke(oComponent,
    "dispose",
    BindingFlags.InvokeMethod,
    arg
    );

    return flag;
}
public static object Invoke(object obj, string method, BindingFlags binding, params object[] par)
{
    return obj.GetType().InvokeMember(method, binding, null, obj, par);
}

但我有以下错误：

Retrieving the COM class factory for component with CLSID {82154420-0FBF-11D4-8313-005004526AB4} failed due to the following error: 80080005.

来源错误：

Line 56: //Create a new ServiceManager Com object using our
Line 57: //ServiceManager type object
Line 58: object oServiceManager = System.Activator.CreateInstance(tServiceManager);
Line 59: //Create our Desktop Com object
Line 60: object oDesktop = Invoke(oServiceManager, "createinstance",

因此，第58行出现错误。

有什么想法吗？

快速猜测：您之前运行应用程序的用户之前从未打开过OpenOffice。尝试以该用户身份登录并运行OpenOffice它会询问几个问题，然后关闭OpenOffice并注销。然后尝试再次运行您的应用....
