Question

我有这个：

public partial class FrmUpload : Form
{
    public FrmUpload()
    {
        InitializeComponent();
    }

    public FrmUpload(Dictionary<string, string> ft) : base()
    {
        foreach (KeyValuePair<string, string> ctrl in ft)
        {
            Controls.Find(ctrl.Key, true)[0].Text = ctrl.Value;
        }
    }

    private void BtnCancelClick(object sender, EventArgs e)
    {
        DialogResult = DialogResult.Cancel;
        Close();
    }

    private void BtnExitClick(object sender, EventArgs e)
    {
        DialogResult = DialogResult.OK;
        Close();
    }
}

我尝试这个时收到索引异常。如果我调试它，我看到InitializeComponent（）不运行..

我主应用中的代码：

var frmUpload = new FrmUpload(FormTextUpload);
if (frmUpload.ShowDialog() != DialogResult.OK) return;

而不是调用基类构造函数：

public FrmUpload(Dictionary<string, string> ft) : base()

调用您自己的无参数构造函数：

public FrmUpload(Dictionary<string, string> ft) : this()

Form问题中的多个表单构造函数
