注解
ToolStripTextBox 是 TextBox 针对在 a ToolStrip. 中托管的优化。 托管控件的属性和事件的子集在 ToolStripTextBox 级别公开，但基础 TextBox 控件可通过 TextBox 该属性完全访问。
该 ToolStripTextBox 控件允许用户在应用程序中输入文本。 此控件具有标准 Windows 文本框控件中未找到的其他功能，包括多行编辑。
通常， ToolStripTextBox 控件用于显示单行文本或接受它作为输入。 可以使用该 Multiline 函数启用要显示或输入的多行文本。 设置 AcceptsTab 属性 AcceptsReturn 以 true 允许在多行 ToolStripTextBox 控件中执行更大的文本操作。
可以通过将MaxLength属性设置为特定数量的字符来限制在控件中ToolStripTextBox输入的文本量。 使用此属性 CharacterCasing 允许用户仅键入大写、仅小写或将大写和小写字符组合到控件中 ToolStripTextBox 。
若要限制控件中 ToolStripTextBox 输入的文本，可以为事件创建事件处理程序 KeyDown ，以验证控件中输入的每个字符。 还可以通过将属性设置为
