StringBuilder 清除性能对比

//测试代码

        StringBuilder stringBuilder = new StringBuilder();

        for (int i = 0; i < 100; i++)
        {
            stringBuilder.Append(i);
        }
        Profiler.BeginSample("Clear");
        stringBuilder.Clear();
        Debug.Log(stringBuilder.ToString());
        Profiler.EndSample();


        for (int i = 0; i < 100; i++)
        {
            stringBuilder.Append(i);
        }
        Profiler.BeginSample("Remove");
        stringBuilder.Remove(0, stringBuilder.Length);
        Debug.Log(stringBuilder.ToString());
        Profiler.EndSample();


        for (int i = 0; i < 100; i++)
        {
            stringBuilder.Append(i);
        }
        Profiler.BeginSample("Length");
        stringBuilder.Length = 0;
        Debug.Log(stringBuilder.ToString());
        Profiler.EndSample();

　　

 

  Remove Lenght 效率和GC比Clear要好
