Crystal reports 为什么我的代码不能在C#中正确运行CristalReport？

我是C#方面的新手，我开发了一些小代码来运行Crystal report，但它挂起了机器，我使用的是VS 2010、access 2007、Crystal report 10和Crystal report 32.OCX

我的代码是：

private void Form12_Load(object sender, EventArgs e)
    {

        ConnectionInfo crConnectionInfo = new ConnectionInfo();
        crConnectionInfo.DatabaseName = Application.ExecutablePath + "\\Pharma.accdb";
        crConnectionInfo.UserID = "";
        crConnectionInfo.Password = "";
        cr1.LogOnInfo.Equals(crConnectionInfo); //("sa", "password", @"MS Access           Database", "pharma");

        ReportDocument reportDocument = new ReportDocument();



        ParameterFields paramFields = new ParameterFields();

        ParameterField paramField = new ParameterField();
        ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue();
        paramField.Name = "CName";
        paramDiscreteValue.Value = "AHmed";
        paramField.CurrentValues.Add(paramDiscreteValue);
        paramFields.Add(paramField);


        this.cr1.RefreshReport();
        this.cr1.Show();
    }

---

不确定这是否是唯一的问题，但该行不正确：

cr1.LogOnInfo.Equals(crConnectionInfo); 

你在这里比较平等

我宁愿尝试：

cr1.LogOnInfo.ConnectionInfo = crConnectionInfo;

它尝试在LogOnInfo对象上分配/设置ConnectionInfo
