我的程序中显示如下所示的代码。弹出一个消息框以显示字段表单的内容。点击OK后,会弹出另一个询问用户信息是否正确的信息。我想把弹出消息框的两个结合起来,显示表单内容并询问信息是否正确,并带有YES / NO按钮。我试过将两者结合起来无济于事。我相信我错过了一个句法概念。有什么想法吗?
//shows contents of form fields
StringBuilder MessageText = new StringBuilder();
MessageText.AppendLine(string.Format("Coil#: {0}", coil_Num.Text));
MessageText.AppendLine(string.Format("Location: {0}", location_box.Text));
MessageText.AppendLine(string.Format("Sub-Area: {0}", sub_area_box.Text));
MessageText.AppendLine(string.Format("Row: {0}", row_Num.Text));
MessageBox.Show(MessageText.ToString());
//asks if info is correct, with a YES/NO button and question mark
DialogResult result1 = MessageBox.Show("Information is correct?",
"Double Check Form Information",
MessageBoxButtons.YesNoCancel,
MessageBoxIcon.Question);
答案 0 :(得分:2)
//shows contents of form fields
StringBuilder MessageText = new StringBuilder();
MessageText.AppendLine(string.Format("Coil#: {0}", coil_Num.Text));
MessageText.AppendLine(string.Format("Location: {0}", location_box.Text));
MessageText.AppendLine(string.Format("Sub-Area: {0}", sub_area_box.Text));
MessageText.AppendLine(string.Format("Row: {0}", row_Num.Text));
MessageText.AppendLine();
MessageText.AppendLine();
//asks if info is correct, with a YES/NO button and question mark
DialogResult result1 = MessageBox.Show(MessageText.ToString() + "Information is correct?",
"Double Check Form Information",
MessageBoxButtons.YesNoCancel,
MessageBoxIcon.Question);
这样的东西?当然,最后一个文本也可以附加到StringBuilder。
如果您只想要是/否按钮,请将MessageBoxButtons.YesNoCancel
更改为MessageBoxButtons.YesNo
。
最后检查结果如下:
switch (result1)
{
case DialogResult.Yes:
// ... Do stuff if Yes is choosen
break;
case DialogResult.No:
// ... Do stuff if No is choosen
break;
case DialogResult.Cancel:
// ... Do stuff if Cancel is choosen
break;
}
当然,您必须添加/删除取消选项,具体取决于您是否包含该按钮。

我假设您想在信息之后提出问题,在这种情况下,您需要将问题附加到stringbuilder,然后再传递给第一个MessageBox中的相关MessageBox arg:
StringBuilder MessageText = new StringBuilder();
MessageText.AppendLine(string.Format("Coil#: {0}", coil_Num.Text));
MessageText.AppendLine(string.Format("Location: {0}", location_box.Text));
MessageText.AppendLine(string.Format("Sub-Area: {0}", sub_area_box.Text));
MessageText.AppendLine(string.Format("Row: {0}", row_Num.Text));
MessageText.AppendLine("Is this information correct?");
DialogResult result1 = MessageBox.Show(MessageText.ToString(),
"Double Check Form Information",
MessageBoxButtons.YesNoCancel,
MessageBoxIcon.Question);
答案 2 :(得分:1)
只是做:
MessageBox.Show(MessageText.ToString(), MessageBoxButtons.YesNoCancel, MessageBoxIcon.Question);
第二个参数(MessageBoxButtons.YesNoCancel)决定它将具有哪些按钮(在这种情况下,是,否和取消)

为什么不简单地连接字符串?
DialogResult result1 = MessageBox.Show(MessageText.ToString() +
"\nInformation is correct?",
"Double Check Form Information",
MessageBoxButtons.YesNoCancel,
MessageBoxIcon.Question);
