1、c#调用科大讯飞的离线语音合成，需要在科大讯飞开放平台:注册、创建应用（获取APPID）、开通离线语音服务、下载 SDK。SDK 中目录如下:bind&ce-xamples.include国lib闊 e-xa m p I es_vs2010_VE.2-012. s I n扁 e-xa m p I e5_v&2010_v5.2-012.5 u oJ Re-adme.txt关于目录结构，讯飞平台的资料库中有介绍。bin目录下有msc.dll动态库。C#调用科大讯飞的语音合成，需要引用 该文件。该文件是C语言生成的dll，C#没办法直接引用。所有需要用 C#重新封装一个TTS.dll,然后再在C#项

2、目中引用封装的TTS.dll。步骤:1在VS中新建一个类库项目(TTS),新建一个类文件(TTS.cs)中的内容如下：Eusing System;using System.Collections.Generic;using System.Linq; using System.Text;using System.Runtime.InteropServices; namespace TTS public enum ErrorCode MSP_SUCCESS = 0, MSP_ERROR_FAIL = -1, MSP_ERROR_EXCEPTION = -2, /* General errors 1
