小编use*_*698的帖子

这是我的控制：

        seriesTraffic = new Series();
        seriesTraffic.Color = Color.Black;
        seriesTraffic.ChartType = SeriesChartType.Spline;
        seriesTraffic.BorderWidth = 2;
        chart1.Series.Add(seriesTraffic);
        chart1.ChartAreas[0].AxisX.MajorGrid.LineColor = Color.White;
        chart1.ChartAreas[0].AxisY.MajorGrid.LineColor = Color.White;
        chart1.ChartAreas[0].AxisX.LabelStyle.Enabled = false;
        chart1.ChartAreas[0].AxisY.LabelStyle.Enabled = false;
        chart1.ChartAreas[0].AxisY.Minimum = 10;
        chart1.ChartAreas[0].AxisX.Maximum = 10;
        chart1.ChartAreas[0].AxisY.Minimum = 10;
        chart1.ChartAreas[0].AxisY.Maximum = 10;
        chart1.ChartAreas[0].AxisY.Interval = 5;
        chart1.ChartAreas[0].AxisY.Interval = 1;
        chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
        chart1.ChartAreas[0].AxisX.IntervalOffsetType = DateTimeIntervalType.Number;

        var chartArea1 = new System.Windows.Forms.DataVisualization.Charting.ChartArea();
        chart1 = new System.Windows.Forms.DataVisualization.Charting.Chart();

        chart1.BackColor = System.Drawing.Color.Black;
        chartArea1.AxisY.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
        chartArea1.AxisY.MinorGrid.Enabled = true;

        chartArea1.AxisX.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
        chartArea1.AxisX2.Enabled = System.Windows.Forms.DataVisualization.Charting.AxisEnabled.True;
        chartArea1.AxisX2.MinorGrid.Enabled = true;

        chartArea1.AxisX.LineColor = …

我有这两个班:

public class A {
    protected int _x;

    public A() {
        _x = 1;
    }

    public A(int x) {
        _x = x;
    }

    public void f(int x) {
        _x += x;
    }

    public String toString() {
        return "" + _x;
    }
}

public class B extends A {
    public B() {
        super(3);
    }

    public B(int x) {
        super.f(x);
        f(x);
    }

    public void f(int x) {
        _x -= x;
        super.f(x);
    }

    public static void main(String[] args) {
        A[] arr = new …

我尝试将选项添加到我的应用程序将文件拖入我的Listbox而不是导航到文件夹,这是我尝试的:

private void Form1_Load(object sender, EventArgs e)
{
    listBoxFiles.AllowDrop = true;
    listBoxFiles.DragDrop += listBoxFiles_DragDrop;
    listBoxFiles.DragEnter += listBoxFiles_DragEnter;
}

private void listBoxFiles_DragEnter(object sender, DragEventArgs e)
{
    e.Effect = DragDropEffects.Copy;
}

private void listBoxFiles_DragDrop(object sender, DragEventArgs e)
{
    listBoxFiles.Items.Add(e.Data.ToString());
}

而不是完整的文件路径 e.Data.ToString() return System.Windows.Forms.DataObject
