Customeformat 不适用于我的日期时间选择器

Question

我遇到了一个问题。我的 windows 表单上有一个 datetimepicker，我将格式属性设置为 Custom，将 CustomeFormat 设置为 dd/MM/yyyy，但是当我运行应用程序时，datetimepicker 显示日历 MM/dd/yyyy。我希望在我的应用程序中使用一致的格式 dd/MM/yyyy 。为了更好地理解，下面是图片。

和运行时日期时间选择器显示如下屏幕

在设计器中生成的代码

 this.engageDateDateTimePicker.CustomFormat = "dd/MM/yyyy";
        this.engageDateDateTimePicker.DataBindings.Add(new System.Windows.Forms.Binding("Value", this.prol01BindingSource, "EngageDate", true, System.Windows.Forms.DataSourceUpdateMode.OnValidation, null, "d"));
        this.engageDateDateTimePicker.Font = new System.Drawing.Font("Microsoft Sans Serif", 8.25F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
        this.engageDateDateTimePicker.Format = System.Windows.Forms.DateTimePickerFormat.Custom;
        this.engageDateDateTimePicker.Location = new System.Drawing.Point(885, 96);
        this.engageDateDateTimePicker.Name = "engageDateDateTimePicker";
        this.engageDateDateTimePicker.Size = new System.Drawing.Size(136, 20);
        this.engageDateDateTimePicker.TabIndex = 27;
        this.engageDateDateTimePicker.ValueChanged += new System.EventHandler(this.engageDateDateTimePicker_ValueChanged);

你能告诉我如何解决这个问题吗

我怀疑您没有在选择器上适当地设置 Format 属性。来自 DateTimePicker.CustomFormat 的文档：

The Format property must be set to DateTimePickerFormat.Custom for this property to affect the formatting of the displayed date and time.
