我遇到了将数据点从一种形式转移到另一种形式的问题。我确保addTagsForm内的按钮有一个公共修饰符。
我已经研究过使用从一种形式到另一种形式的数据值的多种解决方案，我必须从中忽略一些东西。
以下是Form1中的内容：
//Inside Form1
XMLDocGen.PLCData PLC = new XMLDocGen.PLCData();
List<XMLDocGen.TagData> tags = new List<XMLDocGen.TagData>();
AddTagsForm addTagsForm = new AddTagsForm();
addMoreTagsSelected = addTagsForm.addMoreTagsEnabled;
if(addMoreTagsSelected)
{
for(int i= 0; i < 8; i++)
tags.Add(new XMLDocGen.TagData(addTagsForm.addTags[i], addTagsForm.addDataTypes[i], addTagsForm.addElemSizes[i], addTagsForm.addElemCounts[i]));
}
以下是addTagsForm
的内容public void button1_Click(object sender, EventArgs e)
{
addMoreTagsEnabled = true;
var tagNames = new List<TextBox>() { tagNameBoxAMT1, tagNameBoxAMT2, tagNameBoxAMT3, tagNameBoxAMT4, tagNameBoxAMT5, tagNameBoxAMT6, tagNameBoxAMT7, tagNameBoxAMT8 };
var dataTypes = new List<ComboBox>() { dataTypeBoxAMT1, dataTypeBoxAMT2, dataTypeBoxAMT3, dataTypeBoxAMT4, dataTypeBoxAMT5, dataTypeBoxAMT6, dataTypeBoxAMT7, dataTypeBoxAMT1 };
var elemSizes = new List<TextBox>() { elemSizeBoxAMT1, elemSizeBoxAMT2, elemSizeBoxAMT3, elemSizeBoxAMT4, elemSizeBoxAMT5, elemSizeBoxAMT6, elemSizeBoxAMT7, elemSizeBoxAMT8 };
var elemCounts = new List<TextBox>() { elemCountBoxAMT1, elemCountBoxAMT2, elemCountBoxAMT3, elemCountBoxAMT4, elemCountBoxAMT5, elemCountBoxAMT6, elemCountBoxAMT7, elemCountBoxAMT8 };
for (int i = 0; i < 8; i++)
{
addTags.Add(tagNames[i].Text);
addDataTypes.Add(dataTypes[i].Text);
addElemSizes.Add(elemSizes[i].Text);
addElemCounts.Add(elemCounts[i].Text);
}
this.Hide();
}
我已经检查过以确保每个列表都已正确填充。以及列表是公开的。问题是试图从Form1中获取这些值。必须有一些我想念的简单！谢谢你的帮助！

您可以从第一个表单中设置内容：
class Form1
{
...
public void OnButtonPress()
{
var anotherForm = new Form2();
anotherForm.AList = mylist;
anotherForm.BList = myBList;
anotherForm.ShowDialog();
}
}
或者，您可以创建一个类，它封装您想要在两者之间传递的所有内容，因此只传递事物。如果它是强制性的，我会把它放在Form2的构造函数中：
public Form2(MyImportantStuff stuff)
答案 1 :(得分：1)
在您的评论参考后，我为您提供了一个想法。通过在第二种格式public中编写一个简单的Action Form2，您就可以实现目标。下面我展示了一个例子：
使用您想要的集合类型在public全局范围内声明Action Form2，如下所示：
public Action<List<TextBox>, List<ComboBox>> actGetCollection;
使用Form1这样的方式保留一个包含所需集合类型参数的方法：
private void GetCollectionItems(List<TextBox> addTags, List<ComboBox> addDataTypes)
{
//you will get your list items here and do whatever you want with these
}
在您的第二个表单打开的Form1 GetCollectionItems()方法中，将Action方法与Form2中的private void button1_Click(object sender, EventArgs e)
{
//create an instance of your Form2 Form
Form2 obj = new Form2();
//bind your function with the action
obj.actGetCollection = GetCollectionItems;
//then call your Form2's ShowDialog() method to show the form
obj.ShowDialog();
//now your Form2 is opended
}
绑定（假设您在按钮中执行此操作）点击事件）就像这样：
Form2现在，在public void button1_Click(object sender, EventArgs e)
{
addMoreTagsEnabled = true;
var tagNames = new List<TextBox>() { tagNameBoxAMT1, tagNameBoxAMT2, tagNameBoxAMT3, tagNameBoxAMT4, tagNameBoxAMT5, tagNameBoxAMT6, tagNameBoxAMT7, tagNameBoxAMT8 };
var dataTypes = new List<ComboBox>() { dataTypeBoxAMT1, dataTypeBoxAMT2, dataTypeBoxAMT3, dataTypeBoxAMT4, dataTypeBoxAMT5, dataTypeBoxAMT6, dataTypeBoxAMT7, dataTypeBoxAMT1 };
var elemSizes = new List<TextBox>() { elemSizeBoxAMT1, elemSizeBoxAMT2, elemSizeBoxAMT3, elemSizeBoxAMT4, elemSizeBoxAMT5, elemSizeBoxAMT6, elemSizeBoxAMT7, elemSizeBoxAMT8 };
var elemCounts = new List<TextBox>() { elemCountBoxAMT1, elemCountBoxAMT2, elemCountBoxAMT3, elemCountBoxAMT4, elemCountBoxAMT5, elemCountBoxAMT6, elemCountBoxAMT7, elemCountBoxAMT8 };
for (int i = 0; i < 8; i++)
{
addTags.Add(tagNames[i].Text);
addDataTypes.Add(dataTypes[i].Text);
addElemSizes.Add(elemSizes[i].Text);
addElemCounts.Add(elemCounts[i].Text);
}
//call the action
if(actGetCollection != null)
actGetCollection(addTags, addDataTypes);
this.Hide();
}
的button_click事件中执行以下操作：
Form2当您的Form1消失后，您的代码将重新回到Form2来自您GetCollectionItems()的{{1}}事件。现在，在您的angular.module('DatePicker', ['ngAnimate', 'ngSanitize', 'ui.bootstrap']);
