我写了这样的代码：

int count = 1;
while (true)
{
    pointOptions.Message = "'nEnter the end point of the line: ";
    pointOptions.UseBasePoint = true;
    pointOptions.BasePoint = drawnLine.EndPoint;
    pointResult = editor.GetPoint(pointOptions);
    if (pointResult.Status == PromptStatus.Cancel)
    {
        break;
    }
    if (count == 1)
    {
        drawnLine.AddVertexAt(count, pointResult.Value.Convert2d(new Plane()), 0, 0, 0);
        blockTableRecord.AppendEntity(drawnLine);
        transaction.AddNewlyCreatedDBObject(drawnLine, true);
    }
    else
    {
        stretch(drawnLine, pointResult.Value, Point3d.Origin);
    }
    editor.Regen();
    count++;
}

代码运行良好，但要删除图形，我必须键入ESC，我想右键单击或空格键单击以关闭循环。我能做这个吗？

它在PromptPointOptions中。请参阅下面的代码示例：

// Set promptOptions
var pointOptions = new PromptPointOptions("'nSelect Next Point: ");
pointOptions.SetMessageAndKeywords("'nSelect Next Point: or Exit [Y]","Yes");
pointOptions.AppendKeywordsToMessage = true;
pointOptions.AllowArbitraryInput = true;
pointOptions.UseBasePoint = true;
pointOptions.BasePoint = drawnLine.EndPoint;
// While user wants to draw the polyline
while (pointResult.Status != PromptStatus.Keyword)
{
// Get point
pointResult = Editor.GetPoint(pointOptions);
// stop creating polyline
if (pointResult.Status == PromptStatus.Cancel)
    break;
if (count == 1) {
    // Get base point and add to the modelspace
    drawnLine.AddVertexAt(count, pointResult.Value.Convert2d(new Plane()), 0, 0, 0);
    blockTableRecord.AppendEntity(drawnLine);
    transaction.AddNewlyCreatedDBObject(drawnLine, true);
} else
    // Grow the polyline
    stretch(drawnLine, pointResult.Value, Point3d.Origin);
// Regen
editor.Regen();
count++;
}

你想要的是PromptPointOptions.SetMessageAndKeywords，通过更改循环评估，当用户选择"是"时，你就会出现，你可以设置为空格键。

希望这有帮助：）
