Bot:如何在Bot框架中将字段设为只读

public class MyIntent
{
    public string ReadOnlyField { get; set; }

    [ReadOnly]
    public string ReadOnlyProperty { get; set; }
}

public class MyBot : ActivityHandler
{
    protected override async Task OnMessageActivityAsync(ITurnContext<IMessageActivity> turnContext, CancellationToken cancellationToken)
    {
        var myIntent = new MyIntent();
        myIntent.ReadOnlyField = "This field can be read and modified.";
        myIntent.ReadOnlyProperty = "This property can only be read.";

        // Read the values of the fields
        var readOnlyFieldValue = myIntent.ReadOnlyField;
        var readOnlyPropertyValue = myIntent.ReadOnlyProperty;

        // Modify the values of the fields (not allowed for ReadOnlyProperty)
        myIntent.ReadOnlyField = "New value";
        // myIntent.ReadOnlyProperty = "New value"; // This will cause a compilation error

        // ...
    }
}
