maskedTextBox中的百分比显示不正确

Question

我正在尝试在MaskedTextBox中显示在“40.99”中传递的字符串的百分比，但是当它在表单上显示时，它是“409.9％”。

填充价值

 if (_person.Percentage != null)
    maskedTextBoxPercentage.Text = _person.Percentage.ToString();
 else
 {
    maskedTextBoxPercentage.Text = 0.00.ToString();
 }

maskedTextBoxPercentage属性

 this.maskedTextBoxPercentage.Location = new System.Drawing.Point(437, 125);
 this.maskedTextBoxPercentage.Mask = "000.00%";
 this.maskedTextBoxPercentage.Name = "maskedTextBoxPercentage";
 this.maskedTextBoxPercentage.Size = new System.Drawing.Size(129, 20);
 this.maskedTextBoxPercentage.TabIndex = 65;

Answer 1

如果您希望它显示“40.99％”，请将您的面具更改为“00.00％”

Answer 2

试试这个：

try
            {
                this.maskedTextBoxPercentage.Mask = "00.00%";

            }
            catch (Exception)
            {
                this.maskedTextBoxPercentage.Mask = "000%";
            }

或者你也可以试试这个：

try
        {
            this.maskedTextBoxPercentage.Mask = "00.00%";

        }
        catch (Exception)
        {
            this.maskedTextBoxPercentage.Text = "100%";
        }
