javascript - Typescript类不接受参数类型

我正在为数据模型创建新的角度类。
我在新文件中创建了类并在构造函数中初始化它们

export class CreditPoliciesDetails {
    private _fileName : string ="" ;
    private _fileDate : string ="" ;
    private _fileSize : string ="" ;
    private _path : string="";
    private _extention: string="";
    constructor() {
        this._fileDate="fileDate";
        this._fileName="fileName";
        this._fileSize="fileSize";
        this._path="path";
        this._extention="extension";
    }
}

export class CreditPolicies {
    private _document : CreditPoliciesDetails[];
    private _directory: string
    constructor (details: CreditPoliciesDetails[]) {
        this._document = details;
        this._directory="";
    }
    get category() {
        return this._document
    }
    public details (detail) {
        console.log(detail)

        this._document= detail;
    }
}

然后在组件ts文件中声明newCreditPoliciesDetails数组，然后将其传递给files数组，这是CreditPolicies类型的数组。

  details :CreditPoliciesDetails[] = new Array <CreditPoliciesDetails>();

  files : CreditPolicies[] = new Array <CreditPolicies>(this.details);

在vs代码中，当我将new Array <CreditPolicies>(this.details);Argument of type 'CreditPoliciesDetails[]' is not assignable to parameter of type 'CreditPolicies'. Property '_document' is missing in type 'CreditPoliciesDetails[]'.
当我console.logfiles和details时，我得到空数组。
我在等这个格式

[
   {
      "directory":"string",
      "document":[{
         "extension":"string",
         "lastModifiedDate":"string",
         "name":"string",
         "path":"string",
         "size":"0"
      }]
   }
]

最佳答案

必须调用构造函数，而不是将creditpoliciesdetails数组强制转换为creditpolicies数组

details :CreditPoliciesDetails[] = new Array <CreditPoliciesDetails>();

//files : CreditPolicies[] = new Array <CreditPolicies>(this.details);

files : CreditPolicies = new CreditPolicies(this.details);
