## CustomSchemaIds
|
||||
|
||||
CustomSchemaIds方法用于自定义SchemaId，Swashbuckle中的每个Schema都有唯一的Id，框架会使用这个Id匹配引用类型，因此这个Id不能重复。
|
||||
|
||||
默认情况下，这个Id是根据类名得到的（不包含命名空间），因此，当我们有两个相同名称的类时，Swashbuckle就会报错：
|
||||
|
||||
```
|
||||
System.InvalidOperationException: Can't use schemaId "$XXXXX" for type "$XXXX.XXXX". The same schemaId is already used for type "$XXXX.XXXX.XXXX"
|
||||
```
|
||||
|
||||
就是类似上面的异常，一般时候我们都得去改类名，有点不爽，这时就可以使用这个方法自己自定义实现SchemaId的获取，比如，我们自定义实现使用类名的全限定名（包含命名空间）来生成SchemaId，上面的异常就没有了：
|
||||
|
||||
```c#
|
||||
options.CustomSchemaIds(CustomSchemaIdSelector);
|
||||
|
||||
string CustomSchemaIdSelector(Type modelType)
|
||||
{
|
||||
if (!modelType.IsConstructedGenericType) return modelType.FullName.Replace("[]", "Array");
|
||||
|
||||
var prefix = modelType.GetGenericArguments()
|
||||
.Select(genericArg => CustomSchemaIdSelector(genericArg))
|
||||
.Aggregate((previous, current) => previous + current);
|
||||
|
||||
return prefix + modelType.FullName.Split('`').First();
|
||||
}
|
||||
```
