c#中textbox属性

Here we are demonstrating use of MaxLength property of TextBox.

在这里，我们演示了TextBox的MaxLength属性的使用。

MaxLength property of TextBox is used to set maximum number of character that we can input into a TextBox. Limit of MaxLength property is 1 to 32767. By default this property is set to 32767.

TextBox的MaxLength属性用于设置可以输入到TextBox中的最大字符数。 MaxLength属性的限制为1到32767 。 默认情况下，此属性设置为32767 。

Example:

例：

In this example, we took a Windows form that contains a TextBox named txtInput, we are setting MaxLength to 4, that means we cannot enter character more than 4 in this TextBox.

在此示例中，我们采用了Windows窗体，其中包含一个名为txtInput的TextBox ，我们将MaxLength设置为4 ，这意味着我们不能在此TextBox中输入超过4个字符。

Change the property using code:

使用代码更改属性：

private void Form1_Load(object sender, EventArgs e)
{
textInput.MaxLength = 4;
}
