如何将我的getters和setters参数传递给连接类?

问题描述：

我将文本框输入分配给getter，setter也创建了一个连接类.如何将我的getters和setters参数传递给连接类，以便可以在我的主窗体中使用它.

I assigned the textbox inputs to getters and setters also created one connection class. How can I pass my getters and setters parameters to connection class so I can use it inside my mainform.

private string srDatabase = "";
private string srID = "";
private string srPass = "";

public string SDB
{
    get
    {
        return srDatabase;
    }
    set
    {
        srDatabase= value;
    }

public string SID

    get

}

ConnectionClass

 class Connection
    {
        public static OracleConnection GetConnection(string dataSource, string userName, string password)
        {
            OracleConnection con = null;
            if(!string.IsNullOrWhiteSpace(dataSource) && !string.IsNullOrWhiteSpace(userName) && !string.IsNullOrWhiteSpace(password))
                {
                    con = new OracleConnection("Data Source=" + dataSource + ";User Id=" + userName.ToUpper() + ";Password=" + password + ";");
                    return con;
                }

            return con;
        }
    }

MainForm

        UserMembers  = new UserMembers();

        txtSrcUserDatabase.Text = src.srDatabase ;
        txtSrcUserID.Text=src.srID.ToUpper();
        txtSrcUserPassword.Text = src.srPass;



               OracleConnection conn1 = Connection.GetConnection() // **here error**
               conn1.Open();

                using (OracleCommand Names = new OracleCommand("SELECT TABLE_NAME FROM USER_TABLES ORDER BY TABLE_NAME", conn1))
                {
                    using (OracleDataReader reader = Names.ExecuteReader())
                    {                            
                        while (reader.Read())
                        {                                    
                            //Do something                              
                        }
                    }
                }

您的方法GetConnection需要三个参数.您需要将它们传递给方法.

Your method GetConnection requires three parameters. You need to pass them to the method.

UserMembers  src = new UserMembers();

src.srDatabase =txtSrcUserDatabase.Text;
src.srID = txtSrcUserID.Text.ToUpper();
src.srPass = txtSrcUserPassword.Text;
OracleConnection conn1 = Connection.GetConnection(src.srDatabase, src.srID, src.srPass) 
conn1.Open();
......

或者您可以将UserMembers的实例传递给GetConnection方法，从而像这样创建GetConnection的重载

Or you could pass the instance of UserMembers to the GetConnection method creating an overload of GetConnection like this

class Connection
{
    // the first overload that takes 3 string parameters
    public static OracleConnection GetConnection(string dataSource, string userName, string password)
    {
        .... 
    }

    // The second overload that takes an instance of UserMembers
    public static OracleConnection GetConnection(UserMembers src )
    {
        OracleConnection con = null;
        if(!string.IsNullOrWhiteSpace(sr.srDatabase) && !string.IsNullOrWhiteSpace(sr.srID) && !string.IsNullOrWhiteSpace(sr.srPass))
        {
                con = new OracleConnection("Data Source=" + sr.srDatabase + ";User Id=" + sr.srID.ToUpper() + ";Password=" + sr.Pass + ";");
        }
        return con;
    }
}

作为旁注.如果您需要srID成员始终使用大写字母，则可以在setter属性中移动此逻辑，当您尝试回读该成员时，可以不必担心该成员的格式正确

As a side note. If you need the srID member to be always in upper case then move this logic in the setter property, and you could stop to worry about the proper formatting of this member when you try to read it back

public string SID
{
    get  { return srID ; }
    set  { srID = value.ToUpper(); }
}
