DesignerSerializationVisibility属性[Winform]出现问题。

    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
    public String FileName
    {
        get
        {
            return this._fileName;
        }

        set
        {
            File.Move(this._fileName, value);
            this._fileName = value;
        }
    }
