C#Winform 中，兩個form之間參數傳遞

*****A、B 兩個form，A打開B 後，B確定關閉後，B參數傳給A*****

A打開B

private void btnSelectT_Click(object sender, EventArgs e)
        {
            FrmFtpConfigure frmFtpConfigure = new FrmFtpConfigure();
            if (frmFtpConfigure.ShowDialog(this) == DialogResult.OK)
            { 

                ftpUserID = frmFtpConfigure.ftpUserID;
                ftpPassword = frmFtpConfigure.ftpPassword;
                ftpURI = frmFtpConfigure.ftpURI;
            }

            
        }

B關閉

private void btnSave_Click(object sender, EventArgs e)
        {
            
            this.ftpServerIP = this.textBox1.Text;
            this.ftpUserID = this.textBox2.Text;
            this.ftpPassword = this.textBox3.Text;
            this.ftpPort = this.textBox4.Text;
            this.ftpRemotePath = this.textBox5.Text;

            if (ftpPort != "21")
                ftpServerIP = ftpServerIP + ":" + ftpPort;
            ftpURI = "ftp://" + ftpServerIP + "/" + ftpRemotePath + "/";

            this.DialogResult = DialogResult.OK;
            this.Close();        
        }

之後，A就可以看到B傳過來的參數了。
