c#textbox显示百分比

要在C#的TextBox中显示百分比，你可以使用以下代码示例：

double percentage = 0.75; // 假设百分比为75%

// 将百分比转换为字符串，并加上百分号
string percentageString = (percentage * 100).ToString("0.00") + "%";

// 将百分比字符串显示在TextBox中
textBox1.Text = percentageString;

在这个例子中，我们假设百分比为75%，我们将百分比转换为字符串，并使用ToString()方法指定格式为"0.00"来保留两位小数。然后，将百分比字符串赋值给TextBox的Text属性。这样，TextBox就会显示百分比。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
