C# 使用GPConnNet.dll的SQL Server连接

我正在尝试使用GP当前登录的凭据连接到Dynamics GP SQL Server数据库。（上下文）

使用GPConnNet.dll文档中提供的代码，我应该能够获得连接，但对于非sa用户，sa和dynsa无法获得连接。我收到登录失败的sql server错误

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString);
SqlConnection sqlConn = new SqlConnection();
if (sqlConn.State != ConnectionState.Open)
{
    GPConnection.Startup();
    var gpconn = new GPConnection();
    gpconn.Init(<Key1>, <Key2>);
try
{
    sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog);
    gpconn.LoginCompatibilityMode = false;
    gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password);
    if (gpconn.ReturnCode != 1)
         throw new AuthenticationException("Could not authenticate with the GP credentials.");
}
catch (System.Runtime.InteropServices.SEHException)
{
    throw new AuthenticationException("Could not authenticate with the GP credentials.");
}
}

用户是否需要某些东西？GPConnection代码中是否有我遗漏的内容

谢谢

此类将检索连接所需的正确数据

public class GPUser
{
    public readonly static string DataBase = Dynamics.Globals.IntercompanyId.Value;
    public readonly static string UserID = Dynamics.Globals.UserId.Value;
    public readonly static string Password = Dynamics.Globals.SqlPassword.Value;
    public readonly static string DataSource = Dynamics.Globals.SqlDataSourceName.Value;
    public readonly static string ApplicationName = string.Format("{0}{1}", App.ProductName, "(gp)");
    public static SqlConnectionStringBuilder ConnectionString
    {
        get 
        {
            return new SqlConnectionStringBuilder
            {
                DataSource = DataSource,
                UserID = UserID,
                Password = Password,
                ApplicationName = ApplicationName,
                InitialCatalog = DataBase
            };
        }

    }
    public readonly static short CompanyId = Dynamics.Globals.CompanyId.Value;
    public readonly static DateTime UserDate = Dynamics.Globals.UserDate.Value;
}

将GPUser.ConnectionString传递到此代码将创建一个有效的SQLConnection对象，您可以使用该对象连接到GP数据库

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString);
SqlConnection sqlConn = new SqlConnection();
if (sqlConn.State != ConnectionState.Open)
{
    GPConnection.Startup();
    var gpconn = new GPConnection();
    gpconn.Init(<Key1>, <Key2>);
    try
    {
        sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog);
        gpconn.LoginCompatibilityMode = false;
        gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password);
        if (gpconn.ReturnCode != 1)
            throw new AuthenticationException("Could not authenticate with the GP    credentials.");
    }
    catch (System.Runtime.InteropServices.SEHException)
    {
        throw new AuthenticationException("Could not authenticate with the GP credentials.");
    }
}

SqlConnectionStringBuilder cb=新的SqlConnectionStringBuilder（connectionString）；
SqlConnection sqlConn=新的SqlConnection（）；
if（sqlConn.State！=ConnectionState.Open）
{
GPConnection.Startup（）；
var gpconn=新的GPConnection（）；
gpconn.Init（，）；
尝试
{
sqlConn.ConnectionString=string.Format（“数据库={0}”，cb.InitialCatalog）；
gpconn.LoginCompatibilityMode=false；
Connect（sqlConn，cb.DataSource，cb.UserID，cb.Password）；
如果（gpconn.ReturnCode！=1）
抛出新的AuthenticationException（“无法使用GP凭据进行身份验证”）；
}
catch（System.Runtime.InteropServices.SEHException）
{
抛出新的AuthenticationException（“无法使用GP凭据进行身份验证”）；
}
}

我正在使用GPUser类。我得到这个连接字符串：string connection=“data source=Dynamic GP 2010；initial catalog=TWO；persist security info=False；User ID=sa；Password=123”；但是我得到了登录错误。这是作为动态GP 2010的正确数据源吗？是的，看起来差不多正确，“动态GP 2010”是默认的动态GP ODBC32连接名称。你有什么例外？谢谢你的回复！数据源名称不是“Dynamic GP 2010”，即sql数据源名称。如果我对DYNAMCI数据库使用这个连接字符串：Data Source=Rohri；初始目录=两个；持久安全信息=False；用户ID=client1。这很好用。如果使用相同的连接字符串而不是动态连接字符串，则使用两个数据库。“client1”登录失败。您能告诉我为什么只有两个数据库出现错误吗。

SqlConnectionStringBuilder cb = new SqlConnectionStringBuilder(connectionString);
SqlConnection sqlConn = new SqlConnection();
if (sqlConn.State != ConnectionState.Open)
{
    GPConnection.Startup();
    var gpconn = new GPConnection();
    gpconn.Init(<Key1>, <Key2>);
    try
    {
        sqlConn.ConnectionString = string.Format("database={0}", cb.InitialCatalog);
        gpconn.LoginCompatibilityMode = false;
        gpconn.Connect(sqlConn, cb.DataSource, cb.UserID, cb.Password);
        if (gpconn.ReturnCode != 1)
            throw new AuthenticationException("Could not authenticate with the GP    credentials.");
    }
    catch (System.Runtime.InteropServices.SEHException)
    {
        throw new AuthenticationException("Could not authenticate with the GP credentials.");
    }
}
