c# winfom从0学习开发OA、BPM工作流程与自定义表单系统（一）设计前准备

使用DevComponents.DotNetBar2.dll
messagebox样式不能满足当前的要求，所以就把消息框使用了窗体自定义

样式展示

窗体的具体代码

 public partial class FormMessageBox : Office2007Form
    {
        public DialogResult UserChoice { get; private set; }
        public FormMessageBox()
        {
            this.EnableGlass = false;//关键
            InitializeComponent();
        }
        public static DialogResult Show(string message, string title = "", MessageBoxButtons buttons = MessageBoxButtons.OK)
        {
            FormMessageBox messageBox = new FormMessageBox();
            messageBox.lblMessage.Text = message;
            messageBox.Text = title;

            // 设置按钮
            DialogResult result = DialogResult.None;
            switch (buttons)
            {
                case MessageBoxButtons.OK:
                    messageBox.btnCancel.Visible = false;
                    messageBox.btnOK.Text = "确定";
                    break;
                case MessageBoxButtons.OKCancel:
                    messageBox.btnCancel.Text = "取消";
                    messageBox.btnOK.Text = "确定";
                    break;
                case MessageBoxButtons.YesNo:
                    messageBox.btnCancel.Text = "取消";
                    messageBox.btnOK.Text = "确定";
                    break;
                case MessageBoxButtons.YesNoCancel:
                    messageBox.btnCancel.Text = "取消";
                    messageBox.btnOK.Text = "确定";
                    break;
            }

            // 居中显示消息框
            messageBox.StartPosition = FormStartPosition.CenterScreen;

            result = messageBox.ShowDialog();

            return result;
        }

        private void btnOK_Click(object sender, EventArgs e)
        {
            UserChoice = DialogResult.OK;
            this.DialogResult = DialogResult.OK;
        }

        private void btnCancel_Click(object sender, EventArgs e)
        {
            UserChoice = DialogResult.Cancel;
            this.DialogResult = DialogResult.Cancel;
        }
    }

在窗体种如果只是单纯的提示可以直接引用调用

 FormMessageBox.Show("消息框的内容", "信息框", MessageBoxButtons.OK);

如果在窗体中弹出对话框，并且需要判断点击的是确定还是取消来执行相对应的代码则可以使用

        DialogResult result = FormMessageBox.Show("This is a custom message.", "Custom Box", MessageBoxButtons.YesNo);
            if (result == DialogResult.Yes)
            {
                // 用户点击了“是”按钮，执行相应的操作
                // ...
            }
            else if (result == DialogResult.No)
            {
                // 用户点击了“否”按钮，执行相应的操作
                // ...
            }
            else if (result == DialogResult.Cancel)
            {
                // 用户点击了“取消”按钮，执行相应的操作
                // ...
            }
