推荐答案
是的。这应该适合你：
[DllImport（" User32.dll"，EntryPoint =" SendMessage"，CharSet =
CharSet.Auto） ]
private static extern int SendMessageRefRect（IntPtr hWnd，UInt32 Msg，int
wParam，ref RECT rect）;
private const int EM_SETRECT = 0xB3;
public static void SetTextBoxFormatingRectangle（TextBoxBase textbox，
Rectangle rect）
{
RECT rc = new RECT（rect）;
SendMessageRefRect（textbox.Handle，EM_SETRECT，0，ref rc）;
}
你也可以使用EM_SETMARGINS消息，但是这并没有给你
控制顶部和底部。

Yes it is. This should do it for you:
[DllImport("User32.dll", EntryPoint = "SendMessage", CharSet =
CharSet.Auto)]
private static extern int SendMessageRefRect(IntPtr hWnd, UInt32 Msg, int
wParam, ref RECT rect);
private const int EM_SETRECT = 0xB3;
public static void SetTextBoxFormatingRectangle(TextBoxBase textbox,
Rectangle rect)
{
RECT rc = new RECT(rect);
SendMessageRefRect(textbox.Handle, EM_SETRECT, 0, ref rc);
}
You could also use the EM_SETMARGINS message, but that doesn''t give you
control over the top and bottom.

重新在多行文本框中显示文字：
是否可以在左侧或两侧都有边距
双方，所以文字没有到达边界？

非常感谢。我印象深刻！
我已经粘贴在你的代码上面#region Windows Form Designer生成了
代码
我得到了这个编译时的消息：
找不到类型或命名空间名称''RECT''（你是否错过了
使用指令或程序集引用？）

问候，
Patrick。
Thanks a lot. I am impressed!
I have pasted in your code above #region Windows Form Designer generated
code
and I get this message upon compilation:
The type or namespace name ''RECT'' could not be found (are you missing a
using directive or an assembly reference?)

Darn it，I忘了包含那个定义。这是...
public struct RECT
{
public int Left;
public int Top;
public int Right;
public int Bottom;
public RECT（Rectangle rc）{Left = rc 。剩下; Top = rc.Top;对=
rc.Right; Bottom = rc.Bottom; } $ / $
public RECT（int l，int t，int r，int b）{Left = l;顶部= t;右= r;
底部= b; } $ / $
公共覆盖字符串ToString（）{return String.Format（" RECT
（{0}，{1}） - （{2}，{3} ），左，上，右，下）; }
}
