如何将邮件消息拖放到文本框中作为C＃中的输入 [英] How I drag and drop mail message to text box as input in C#

问题描述

你好，

我如何将邮件拖放到文本框中作为c＃中的输入，所以之后我可以将其保存在其他路径中。

我尝试我在互联网上找到的所有解决方案，但它没有用。

我希望能够从资源管理器（现在可以正常工作）或邮件项目拖放文件，

或邮件附件（它可以工作）



我尝试过：



公共类MyTextBox：TextBox

{

public Outlook.Application _Outlook = new Outlook.Application（）;

public MyTextBox（）

{

AllowDrop = true;

Multiline = true;

DragDrop + = new DragEventHandler（MyTextBox_DragDrop）;

DragEnter + = new DragEventHandler（MyTextBox_DragEnter ）;



}

...

..

..

private void MyTextBox_DragEnter（object sender，DragEventArgs e）

{

//对于这个程序，我们允许从资源管理器中删除一个文件

if（e.Data.GetDataPresent（DataFormats.FileDrop））

{e.Eff ect = DragDropEffects.Copy; }

//或者告诉我们它是否是一个Outlook附件下降

else if（e.Data.GetDataPresent（FileGroupDescriptor））

{e.Effect = DragDropEffects.Copy; }

//或以上都不是

其他



{e.Effect = DragDropEffects.None;



}

// e.Effect = DragDropEffects.Copy;

}

..

..

private void MyTextBox_DragDrop（object sender，DragEventArgs e）

{

<如果（e.Data.GetDataPresent（DataFormats.FileDrop，false）== true）

{

this.Text =（（string []）e.Data.GetData（DataFormats.FileDrop））[0];

}

else if（e.Data。 GetDataPresent（FileGroupDescriptor））

{



流theStream =（流）e.Data.GetData（FileGroupDescriptor）;

byte [] fileGroupDescripto r = new byte [512];

theStream.Read（fileGroupDescriptor，0,512）;

//用于从FileGroupDescriptor块构建文件名

StringBuilder fileName = new StringBuilder（）;

//这个技巧获取传递的附件的文件名

for（int i = 76; fileGroupDescriptor [i]！= 0; i ++）

{fileName.Append（Convert.ToChar（fileGroupDescriptor [i]））; } $ / $
theStream.Close（）;

string path = Path.GetTempPath（）;

//将zip文件放入临时目录

string theFile = path + fileName.ToString（）;

this.Text = theFile;

if（theFile.Contains（。msg） ））

{



Outlook.Explorer oExplorer = _Outlook.ActiveExplorer（）;

Outlook.Selection oSelection = oExplorer.Selection;

Outlook.MailItem mi =（Outlook.MailItem）oSelection;

mi.SaveAs（Path .GetTempPath（）+ mi.Subject.ToString（）+。msg，Outlook.OlSaveAsType.olMSG）;

theFile = Path.GetTempPath（）+ mi.Subject.ToString（）+ .msg;



this.Text = theFile;

FileInfo tempFile = new FileInfo（theFile）;

if（！tempFile.Exists == true）

{

MessageBox.Show（文件未创建！+ Environment.NewLine + theFile）;

}

}

其他

{



MemoryStream ms =（MemoryStream）e.Data.GetData（

FileContents，true）;



byte [] fileBytes = new byte [ms.Length];



ms.Position = 0;

ms.Read（fileBytes，0，（int）ms.Length ）;



FileStream fs = new FileStream（theFile，FileMode.Create）;

fs.Write（fileBytes，0，（int） fileBytes.Length）;



fs.Close（）; //关闭文件



FileInfo tempFile = new FileInfo（theFile）;



//总是好的确保我们实际创建了文件

if（！tempFile.Exists == true）

{

MessageBox.Show（File is没创建！+ Environment.NewLine + theFile）;

}

}

}

解决方案

你可以从这里开始使用C＃进行Outlook拖放 [ ^

hello,
How can I drag and drop mail message to text box as input in c# , so after that I can save it in a other path.
I try all the solution I found in internet and it did not work.
I want to be able to drag and drop file from explorer (it work now) or mail item,
or mail attachments ( it work)

What I have tried:

public class MyTextBox : TextBox
{
public Outlook.Application _Outlook = new Outlook.Application();
public MyTextBox()
{
AllowDrop = true;
Multiline = true;
DragDrop += new DragEventHandler(MyTextBox_DragDrop);
DragEnter += new DragEventHandler(MyTextBox_DragEnter);

}
...
..
..
private void MyTextBox_DragEnter(object sender, DragEventArgs e)
{
// for this program, we allow a file to be dropped from Explorer
if (e.Data.GetDataPresent(DataFormats.FileDrop))
{ e.Effect = DragDropEffects.Copy; }
// or this tells us if it is an Outlook attachment drop
else if (e.Data.GetDataPresent("FileGroupDescriptor"))
{ e.Effect = DragDropEffects.Copy; }
// or none of the above
else

{ e.Effect = DragDropEffects.None;

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

{
if (e.Data.GetDataPresent(DataFormats.FileDrop, false) == true)
{
this.Text = ((string[])e.Data.GetData(DataFormats.FileDrop))[0];
}
else if (e.Data.GetDataPresent("FileGroupDescriptor"))
{

Stream theStream = (Stream)e.Data.GetData("FileGroupDescriptor");
byte[] fileGroupDescriptor = new byte[512];
theStream.Read(fileGroupDescriptor, 0, 512);
// used to build the filename from the FileGroupDescriptor block
StringBuilder fileName = new StringBuilder("");
// this trick gets the filename of the passed attached file
for (int i = 76; fileGroupDescriptor[i] != 0; i++)
{ fileName.Append(Convert.ToChar(fileGroupDescriptor[i])); }
theStream.Close();
string path = Path.GetTempPath();
// put the zip file into the temp directory
string theFile = path + fileName.ToString();
this.Text = theFile;
if (theFile.Contains(".msg"))
{

Outlook.Explorer oExplorer = _Outlook.ActiveExplorer();
Outlook.Selection oSelection = oExplorer.Selection;
Outlook.MailItem mi = (Outlook.MailItem)oSelection;
mi.SaveAs(Path.GetTempPath() + mi.Subject.ToString() + ".msg",Outlook.OlSaveAsType.olMSG);
theFile = Path.GetTempPath() + mi.Subject.ToString() + ".msg";

this.Text = theFile;
FileInfo tempFile = new FileInfo(theFile);
if (!tempFile.Exists == true)
{
MessageBox.Show("File was not created!" + Environment.NewLine + theFile);
}
}
else
{

MemoryStream ms = (MemoryStream)e.Data.GetData(
"FileContents", true);

byte[] fileBytes = new byte[ms.Length];

ms.Position = 0;
ms.Read(fileBytes, 0, (int)ms.Length);

FileStream fs = new FileStream(theFile, FileMode.Create);
fs.Write(fileBytes, 0, (int)fileBytes.Length);

fs.Close(); // close the file

FileInfo tempFile = new FileInfo(theFile);

// always good to make sure we actually created the file
if (!tempFile.Exists == true)
{
MessageBox.Show("File was not created!" + Environment.NewLine + theFile);
}
}
}
