Question

背景

我切换了操作系统，但我的C＃表单应用程序运行正常，但无法正常运行。我在Windows上使用Visual Studio 2017，现在在Ubuntu上使用最新版本的MonoDevelop。

问题

我有一个主窗体，第二个窗体和第三个窗体，这些窗体应用户要求按此顺序打开。第三个窗口仅显示一个图表，除了调整大小/关闭之外，没有其他交互按钮。

运行第三个窗口后，其BeginInit()方法将调用主窗体Dispose(bool)方法，然后关闭主窗口，然后关闭第二个窗口，应用程序将挂起，直到我停止从monodevelop GUI调试为止。尽管我对MonoDevelop刚起步，所以我似乎找不到任何能指出发生这种情况的原因的信息，所以也许我没有找到合适的位置。

代码

主要形式：

// Open Second Window called "Diagnostics"
private void Plots_Click(object sender, EventArgs e)
{
    Application.Run(new Diagnostics(xmlDirectory));
}

第二个“诊断”表格：

// Set up stuff and run the Third window called "ChartDisplay"
private void GenerateChart_Click(object sender, EventArgs e)
{
    // irrelevant code

    Application.Run(new ChartDisplay(datapoints, horizontalChoice, verticalChoice));

}

第三种“ ChartDisplay”表格：

public ChartDisplay(List<object[]> data, string xAxisLabel, string yAxisLabel)
{
        InitializeComponent();

        // irrelevant code that doesn't get run
}

ChartDisplay.Designer：

private void InitializeComponent()
{
    System.Windows.Forms.DataVisualization.Charting.ChartArea chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
    System.Windows.Forms.DataVisualization.Charting.Legend legend1 = new System.Windows.Forms.DataVisualization.Charting.Legend();
    System.Windows.Forms.DataVisualization.Charting.Series series1 = new System.Windows.Forms.DataVisualization.Charting.Series();
    this.chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();
    ((System.ComponentModel.ISupportInitialize)(this.chart1)).BeginInit(); // last line to get called
    // ...
}

调试

进入((System.ComponentModel.ISupportInitialize)(this.chart1)).BeginInit();中的Chart.Designer.cs调用InitializeComponent()会直接跳到前面提到的主要形式Dispose(bool)方法。从那里进入所有内容只需循环执行Dispose函数，直到关闭主窗口，然后关闭所有其他窗口，使应用程序挂起。

由于篇幅太长，我将调用堆栈放在帖子的底部Dispose(bool)上。

我尝试过的事情

关于相似问题，我唯一能找到的帮助是建议使用Application.Run(Form)，而不是创建一个新的Form对象并调用它的Show()方法。如上所示，我切换到此方法，仍然没有骰子。

我尝试添加一种方法来防止窗户被关闭：

private void MainWindow_FormClosing(object sender, FormClosingEventArgs e)
{
    this.Hide();
    e.Cancel = true;
}

但是这什么也没做，甚至没有被调用。

单步执行并不能真正产生成果。看来我实际上无法进入引起BeginIinit()
