+# RHIDevice::CompileShader
+
+```cpp
+virtual RHIShader* CompileShader(const ShaderCompileDesc& desc) = 0;
+```
+
+编译着色器程序。
+
+**参数：**
+- `desc` - 着色器编译描述符，包含入口点、配置文件、源文件等
+
+**返回：** 新创建的着色器指针，失败返回 `nullptr`
+
+**复杂度：** O(n) - 取决于着色器代码复杂度
+
+**示例：**
+
+```cpp
+ShaderCompileDesc shaderDesc;
+shaderDesc.entryPoint = L"main";
+shaderDesc.profile = L"vs_6_0";
+shaderDesc.fileName = L"shaders/vertex.hlsl";
+shaderDesc.macros = {};
+
+RHIShader* vertexShader = device->CompileShader(shaderDesc);
+if (!vertexShader->IsValid()) {
+    // 处理编译错误
+    vertexShader->Shutdown();
+}
+```
