+# Model Deployment with C or C# API
+
+Fastdeploy provideds C and C# API to support deployment with multiple programming languages, and this feature is included since version 1.0.4. C API is compiled and included in fastdeploy dynamic library by default. If you want to compile fastdeploy with C and C# API manually, compile it with options -DWITH_CAPI=ON and -DWITH_CSHARPAPI=ON. For more information about how to use C and C# API to deploy models, please refer to

+# 使用C或C# API进行模型部署
+
+FastDeploy提供了C API以及C# API满足多语言部署的需求，这一特性从FastDeploy v1.0.4版本开始进行了支持。默认情况下，C API被编译进入了fastdeploy的动态库。
+如果希望手动编译FastDeploy，并且集成C和C# API进去，只需要打开编译开关-DWITH_CAPI=ON, -DWITH_CSHARPAPI=ON。关于如何安装和使用C和C# API，可以参考下列文档：
