一个文本属性TextBox允许您访问整个文本，获取和设置机器人 - 所以您需要做的就是决定放置它的位置，并插入日期字符串。

例如：

The Text property of a TextBox gives you access to the whole text, bot for get and set - so all you need to do is decide where you want to put it, and "insert" the date string.
For example:

myTextBox.Text = time.ToString("G") + myTextBox.Text;

将它插入前面。

或：

Will insert it at the front.
Or:

myTextBox.Text = myTextBox.Text.Replace("%%", time.ToString("G"));

将替换：

Would replace:

It is %% at the moment

With

It is 20/02/2014 13:02:10 at the moment

您可以使用文本框的SelectionStart属性。



例如：

You can use the SelectionStart property of the textbox.

For example:

txtWritingBox.Text = txtWritingBox.Text.Insert(txtWritingBox.SelectionStart, time.ToString("G"));

string inginsertText = "Blah Blah Blah Text";
int selectionIndex = textBox1.SelectionStart;
textBox1.Text = textBox1.Text.Insert(selectionIndex, insertText);
textBox1.SelectionStart = selectionIndex + insertText.Length;
