如果您想让用户无法修改某些文本的文本框，只需将其添加到末尾(或类似内容)，则该文本框就不好了选择-它不能开箱即用，添加该功能将是笨拙".

但是，有 MaskedTextBox [

If you mean that you want a text box where the user cannot modify some of the text, just add to the end (or similar) then the text box is not a good choice - it can''t do it out of the box, and it would be "clumsy" to add that functionality.

However, there is the MaskedTextBox[^] which can: look at the Mask property.

For example, setting the Mask to "FIXED TEXT: AAAAA : MORE" means that the user can enter only 5 alphanumeric characters, which will always be in the area between the '':'' characters.
