如何将参数从一个类传递到另一个类 [英] How to pass a parameter from one class to another

问题描述

我希望从按下一个按钮到主按钮时从窗口获取一个值（1或0）但在运行时说"参数无效"时会出现错误。我不确定我做错了什么，除了显而易见的是我实现参数的方式有一些
错误。

< pre class ="prettyprint">使用System;
使用System.Windows.Forms;

//使用System.Drawing.Imaging成像
;使用System.Drawing
;

命名空间DataCollection
{
public partial class SortpBoundaryImages：Form
{
public int tempFlag = 0;

public int TmpFlag
{
get
{
return tempFlag;
}
设置
{
tempFlag = value;
}
}


public SortpBoundaryImages（）
{
InitializeComponent（）;
//将图像加载到表格中
位图bmp =新位图（@"C：\ ELEC Project \ temp.bmp"）;
pictureBox1.Image = bmp;
bmp.Dispose（）;
}

//公共类ResultFromFrmMain
// {
// public DialogResult Result {get;组; }
// public int Getvalue {get;组; }
//}

private void button1_Click（object sender，EventArgs e）
{
//如果用户将图像分类为重要点，则存储它在PboundaryIntrest文件夹中
int fileNum = Data.ImageCount.ImageSum（" PboundaryIntrest"）;

位图bmp =新位图（@"C：\ ELEC Project \ temp.bmp"）;

bmp.Save（@" C：\ ELEC Project \ PboundaryIntrest\" + fileNum +" .bmp"）;

bmp.Dispose（）;

关闭（）;
}

private void pictureBox1_Click（object sender，EventArgs e）
{

}

private void pointOther_Click（object sender，EventArgs e）
{
//如果用户将点分类为不重要，则将其存储为普通P边界
var tFalg = new SortpBoundaryImages（）;
tFalg.tempFlag = 1;

关闭（）;
}
}
class DataCollection

{
public static void main（）
{
//添加临时图像获取者
var Psort = new SortpBoundaryImages（）;
Psort.Show（）;
var Tflag = Psort.tempFlag;
string gt =" \ nboolvaluer is" + Tflag;
Application.ShowAlertDialog（gt）;
}
}
}

解决方案

至少尝试这些变化：

private void pointOther_Click（object sender，EventArgs e）

{

   TmpFlag = 1;

   关闭（）;

}

。 。 。

Psort.ShowDialog（）;

var Tflag = Psort.TmpFlag;

I want to get a value (1 or 0) from windows from when a button in pressed back into main but it comes up with an error when run saying "parameter is not valid". I am not sure what I am doing wrong apart from the obvious that there is something wrong with how I am implementing the parameter.

using System;
using System.Windows.Forms;

//Imaging
using System.Drawing.Imaging;
using System.Drawing;

namespace DataCollection
{
    public partial class SortpBoundaryImages : Form
    {
        public int tempFlag = 0; 

        public int TmpFlag
        {
            get
            {
                return tempFlag;
            }
            set
            {
                tempFlag = value;
            }
        }


        public SortpBoundaryImages()
        {
            InitializeComponent();
            //Load up the image into the form
            Bitmap bmp = new Bitmap(@"C:\ELEC Project\temp.bmp");
            pictureBox1.Image = bmp;
            bmp.Dispose();
        }

        //public class ResultFromFrmMain
        //{
        //    public DialogResult Result { get; set; }
        //    public int Getvalue { get; set; }
        //}

            private void button1_Click(object sender, EventArgs e)
        {
            //If the users classifies the image as an impotant point then store it in the PboundaryIntrest folder
            int fileNum = Data.ImageCount.ImageSum("PboundaryIntrest");

            Bitmap bmp = new Bitmap(@"C:\ELEC Project\temp.bmp");

            bmp.Save(@"C:\ELEC Project\PboundaryIntrest\"+ fileNum +".bmp");

            bmp.Dispose();

            Close();
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {

        }

        private void pointOther_Click(object sender, EventArgs e)
        {
            //If the user classifies the point as not important then store it as a normal P boundary
            var tFalg = new SortpBoundaryImages();
            tFalg.tempFlag = 1;

            Close();
        }
    }
    class DataCollection

    {
        public static void main()
        {
            //add in temp image taker
            var Psort = new SortpBoundaryImages();
            Psort.Show();
            var Tflag = Psort.tempFlag;
            string gt = "\nboolvaluer is " + Tflag;
            Application.ShowAlertDialog(gt);
        }
    }
}

解决方案

Try at least these changes:

private void pointOther_Click(object sender, EventArgs e)

{

   TmpFlag = 1;

   Close();

}

. . .

Psort.ShowDialog();

var Tflag = Psort.TmpFlag;
