Angular 无法读取属性'；推动'；当我调用this.users时未定义的

调用push方法时出错

ng:///AppModule/ManageUser_Host.ngfactory.js:5 ERROR TypeError: Cannot read property 'push' of undefined

代码如下所示：

public users: User[];

this.users.push({"UserId":2,"FirstName":"string","FullName":"string","LastName":"string","EmailAddress":"string",
        "GEID":"string",
        "RITSID":"string",
        "SOEID":"string",
        "RoleID": 1,
        "RoleName":"string",
        "IsActive":true,
        "ModifyingUserId":"string",
        "CreatedBy":"string",
        "CreatedDate":"string",
        "EmailID":"string",       
        "Name": "string",
        "Email": "string",
        "Roles":"any",
        "Manager":"string"});

    console.log(this.users);

您只是在定义它，因此默认情况下该值为

未定义

  public users: User[];

只需添加一个值，然后重试

public users: User[]= [];

快乐编码：）

您需要首先创建空数组，请尝试公共用户：User[]=[]；值得在发布问题之前进行搜索。。。指的是副本。
