C# Don'；无法加载fbembed.dll，但它'；它在测试用例中是好的吗？

我正在使用嵌入在.net应用程序中的FireBird。我的联系人是：

代码是：

    public class ImDb{
    private static FbConnection _fbConnection;
    public static FbConnection IMManagerConnection() {
        var fbConnStringBuilder = new FbConnectionStringBuilder();
        fbConnStringBuilder.ServerType = FbServerType.Embedded;
        fbConnStringBuilder.UserID = "sysdba";
        fbConnStringBuilder.Password = "masterkey";
        //fbConnStringBuilder.ClientLibrary = @"fbembed.dll";
        fbConnStringBuilder.Database = @"IMMANAGER.FDB";

        _fbConnection = new FbConnection(fbConnStringBuilder.ConnectionString);
        return _fbConnection;
    }
}

    [Test]
    public void SimSymbolTest(){
        FbConnection fbc=IMManager.Common.ImDb.IMManagerConnection();
        fbc.Open();
        Console.WriteLine("The Server Version is :" + fbc.ServerVersion);
        Console.WriteLine("The database is :" + fbc.Database);
        Console.WriteLine("The DataSource is :" + fbc.DataSource);
        Console.WriteLine("The Version Number is: " + fbc.ServerVersionNumber);
        fbc.Close();
    }

  private DataTable ExeQuery(string sqlString){
        DataSet ds = new DataSet();
        FbConnection fbc = ImDb.IMManagerConnection();
        try {
            fbc.Open();
            FbTransaction fbt = fbc.BeginTransaction();
            FbCommand fbcmd = new FbCommand(sqlString, fbc, fbt);
            FbDataAdapter fbda = new FbDataAdapter(fbcmd);
            fbda.Fill(ds);
            fbt.Commit();
        } catch (Exception ex) {
            MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
        } finally {
            fbc.Close();
        } 
        return ds.Tables[0];
    }

这是我的测试用例：

代码是：

    public class ImDb{
    private static FbConnection _fbConnection;
    public static FbConnection IMManagerConnection() {
        var fbConnStringBuilder = new FbConnectionStringBuilder();
        fbConnStringBuilder.ServerType = FbServerType.Embedded;
        fbConnStringBuilder.UserID = "sysdba";
        fbConnStringBuilder.Password = "masterkey";
        //fbConnStringBuilder.ClientLibrary = @"fbembed.dll";
        fbConnStringBuilder.Database = @"IMMANAGER.FDB";

        _fbConnection = new FbConnection(fbConnStringBuilder.ConnectionString);
        return _fbConnection;
    }
}

    [Test]
    public void SimSymbolTest(){
        FbConnection fbc=IMManager.Common.ImDb.IMManagerConnection();
        fbc.Open();
        Console.WriteLine("The Server Version is :" + fbc.ServerVersion);
        Console.WriteLine("The database is :" + fbc.Database);
        Console.WriteLine("The DataSource is :" + fbc.DataSource);
        Console.WriteLine("The Version Number is: " + fbc.ServerVersionNumber);
        fbc.Close();
    }

  private DataTable ExeQuery(string sqlString){
        DataSet ds = new DataSet();
        FbConnection fbc = ImDb.IMManagerConnection();
        try {
            fbc.Open();
            FbTransaction fbt = fbc.BeginTransaction();
            FbCommand fbcmd = new FbCommand(sqlString, fbc, fbt);
            FbDataAdapter fbda = new FbDataAdapter(fbcmd);
            fbda.Fill(ds);
            fbt.Commit();
        } catch (Exception ex) {
            MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
        } finally {
            fbc.Close();
        } 
        return ds.Tables[0];
    }

在我的应用程序中，这是错误的！！报表不加载fbembed.dll

代码是：

    public class ImDb{
    private static FbConnection _fbConnection;
    public static FbConnection IMManagerConnection() {
        var fbConnStringBuilder = new FbConnectionStringBuilder();
        fbConnStringBuilder.ServerType = FbServerType.Embedded;
        fbConnStringBuilder.UserID = "sysdba";
        fbConnStringBuilder.Password = "masterkey";
        //fbConnStringBuilder.ClientLibrary = @"fbembed.dll";
        fbConnStringBuilder.Database = @"IMMANAGER.FDB";

        _fbConnection = new FbConnection(fbConnStringBuilder.ConnectionString);
        return _fbConnection;
    }
}

    [Test]
    public void SimSymbolTest(){
        FbConnection fbc=IMManager.Common.ImDb.IMManagerConnection();
        fbc.Open();
        Console.WriteLine("The Server Version is :" + fbc.ServerVersion);
        Console.WriteLine("The database is :" + fbc.Database);
        Console.WriteLine("The DataSource is :" + fbc.DataSource);
        Console.WriteLine("The Version Number is: " + fbc.ServerVersionNumber);
        fbc.Close();
    }

  private DataTable ExeQuery(string sqlString){
        DataSet ds = new DataSet();
        FbConnection fbc = ImDb.IMManagerConnection();
        try {
            fbc.Open();
            FbTransaction fbt = fbc.BeginTransaction();
            FbCommand fbcmd = new FbCommand(sqlString, fbc, fbt);
            FbDataAdapter fbda = new FbDataAdapter(fbcmd);
            fbda.Fill(ds);
            fbt.Commit();
        } catch (Exception ex) {
            MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
        } finally {
            fbc.Close();
        } 
        return ds.Tables[0];
    }

这是我的目录：

请帮帮我！提前谢谢

然后修改连接代码，添加ClientLibrary的值：

测试用例运行正常

但在应用程序中，该错误再次发生。

Firebird 2.5嵌入式的一组最小文件：

INTL\fbintl.conf
INTL\fbintl.dll
fbembed.dll
firebird.msg
ib_util.dll
icudt30.dll
icuin30.dll
icuuc30.dll
Microsoft.VC80.CRT.manifest
msvcp80.dll
msvcr80.dll

在您的情况下，microsoft文件丢失。

没有解决方案

我必须更改FireBird服务器的版本

没关系

顺便说一句，我在我的应用程序中使用的是VisualWebGUI，路径问题可能与此有关。也许VWG和IIS之间有不同？我不知道，只是guest；）

对于Windows应用程序，它将在.exe文件所在的文件夹中查找dll

对于Web应用，可以设置连接字符串的ClientLibrary属性：

---

connectionString=“ServerType=1；User=SYSDBA；Password=masterkey；dialogy=3；Database=；ClientLibrary=“

请使用实际代码而不是屏幕截图进行更新。。。这允许其他人搜索相同的问题。我看到了一些ASP.NET片段。您确定正在从此目录运行应用程序吗？可能它实际上是从不同的目录运行的-IIS（Express）等。这些文件不是必需的。这些可能与其他产品一起安装。我认为问题的关键是：测试用例没有问题，但只有在应用程序中才有问题。然后我将msv*.dll的文件复制到bin目录，问题仍然存在。在您的应用程序中，分配客户端库的行注释为//fbConnStringBuilder.ClientLibrary=@“fbedded.dll”；为什么？
