c# - 捕获 MessageBox 结果

Question

我正在尝试让用户确认他们是否要使用 MessageBox 删除产品并捕获其结果。这是我的代码:

// Confirm if the user really wants to delete the product
DialogResult result = MessageBox.Show("Do you really want to delete the product \"" + productName + "\"?", "Confirm product deletion", MessageBoxButtons.YesNo, MessageBoxIcon.Warning);
if (result == DialogResult.OK)
{
    MessageBox.Show("deleted");
}

当我运行代码并尝试删除产品时，删除永远不会显示。在 MSDN 页面上它说使用 MessageBoxResult 而不是 DialogResult 但 Visual Studio 不识别 MessageBoxResult，我使用 DialogResult 在我打开文件对话框的代码中的其他地方。显然，这不是检查它的正确方法。

你必须请求 DialogResult.Yes

// Confirm if the user really wants to delete the product
DialogResult result = MessageBox.Show("Do you really want to delete the product \"" +     productName + "\"?", "Confirm product deletion", MessageBoxButtons.YesNo,  MessageBoxIcon.Warning);
if (result == DialogResult.Yes)
{
    MessageBox.Show("deleted");
}
