Typescript 错误 TS2449: Class 'x' 在其声明之前使用，并确保在此处声明 'X'

Question

Such this question is asked before here and here but it can't help. my case is different.

I have one typescript file containing 40 DTO class converted from C# file, like:

//model.ts

export class A extends B
{
//...
}

export class B
{
//...
}

export class C
{
//...
}
export class D extends C
{
//...
}

//more classes

}

When I try to compile the file using tsc I get an error:

model.ts:3:24 - error TS2449: Class 'B' used before its declaration.
3 export class A extends B
                         ~
  model.ts:8:14
    8 export class B
                   ~
    'B' is declared here.

If I Generated the c# class as interface, compilation success without error. tsc say that class B is declared here, but can't use it.

Sure, editing the file and moving the B class before A class, I get no error.

I want to avoid the manual editing of the converted file.

My Question: Is there an option in tsc configuration or other way to avoid this error and the manual editing of the generated file?

Answer 1

I find a good tool that reorder the classes based on the dependency, so parent (base class) is written before the child.

It's csharp2ts by @Rafael Salguero Iturrios , and it's an extension to VScode.

I converted the c# file and the error disappear
