Question

这里的代码给出了错误“{”无效的URI：无法解析主机名。“}”

interface User {
  id: string;
  name: string;
  Lastname: string;
}

class UsersCollection {

  private id = 15;

  constructor(private _users: Array<User> = []) {

  }

  public create(name: string, lastName: string): User {
    let user =  {
      id: this.id++,
      name: name,
      Lastname: lastName
    };
    this._users.push(user);
    return user;
  }

  public searchUser(name: string, lastName: string): User | null {
    return this._users.find((user) => {
      return user.name == name && user.Lastname == lastName;
    })
  }

  public getOrCreate(name: string, lastName: string) {
    let user = this.searchUser(name, lastName);
    if (user) {
      return user;
    }
    return this.create(name, lastName);
  }

  public size(){
    return this._users.length;
  }
}


let users = new UsersCollection([{
  'id': '1',
  'name': 'rob',
  'Lastname': 'Xyz'
},
  {
    'id': '2',
    'name': 'xyz',
    'Lastname': 'abc'
  }]);

// Existing user
console.log(users.getOrCreate('rob','Xyz'));
console.log(users.size() == 2);

// Add new one
console.log(users.getOrCreate('rob','123'));
console.log(users.size() == 3);

这里的ftp密码有一个@字符，当删除时允许这段代码继续。但是密码有一个@字符，那我怎么能让它工作呢？

您需要对@符号进行十六进制编码：

string encodedPassword = "p@ssword".Replace("@", "%40");

FtpWebRequest FTPRequest = (FtpWebRequest)FtpWebRequest.Create("ftp://" 
    + "user123" +
    ":" + encodedPassword + "@" + downloadUri);

（根据安德鲁的建议）如果你想抓住更多＆＃34;专业＆＃34;字符：

添加对System.Web的引用并使用以下内容：

string encodedPassword = HttpUtility.UrlEncode("p@ssword");

FtpWebRequest FTPRequest = (FtpWebRequest)FtpWebRequest.Create("ftp://" 
    + "user123" +
    ":" + encodedPassword + "@" + downloadUri);

或者，甚至更好：

string userName = "user123";
string password = "p@ssword";
string ftpPath = string.Format("ftp://{0}:{1}@{2}", userName, password, downloadUri);

var ftpRequest = (FtpWebRequest)FtpWebRequest.Create(HttpUtility.UrlEncode(ftpPath));

“主机名无法解析”来自“ftp”
