[英]Trim white space and return errors in c#
I'm moving from PHP (procedural) to C# and I've a number of errors in the following block - what am I doing wrong? 我正在从PHP(过程性)转移到C#,并且在以下块中出现了许多错误-我在做什么错?
Objective is to pass in username and password values, then to trim, validate and return a list of errors (I'm using the dictionary to build an array of errors). 目的是传递用户名和密码值,然后修剪,验证并返回错误列表(我正在使用字典来构建错误数组)。
"else" = "Type or namespace definition, or end of file expected". “ else” =“类型或名称空间定义,或预期的文件结尾”。
public class Login (string InUserName, string InUserPass) { string varUserName; string varUserPass; // Dictionary object is c# equivalent of PHP's 'array["key"] = "value"' Dictionary<string, string> errMsg = new Dictionary<string, string>(); varUserName = "123qwe"; varUserName = varUserName.Trim(); if ((varUserPass == "") && (varUserName == "")) { errMsg.Add("Username", "Username cannot be blank"); errMsg.Add("Password", "Username cannot be blank"); } else { if (varUserName == "") { errMsg.Add("Username", "Username cannot be blank"); } if (varUserPass == "") { errMsg.Add("Password", "Password cannot be blank"); } } }
Thanks Newbie Matt 谢谢新手马特
The problem is, that you do everything in your class. 问题是,您需要在课堂上做所有的事情。 You can't do logic in your class. 您不能在课堂上做逻辑。 Put your code in a Method. 将您的代码放在方法中。 Like so: 像这样:
public class Login
{
string varUserName;
string varUserPass;
// Dictionary object is c# equivalent of PHP's 'array["key"] = "value"'
Dictionary<string, string> errMsg = new Dictionary<string, string>();
public Dictionary<string, string> LogMeIn()
{
varUserName = "123qwe";
varUserName = varUserName.Trim();
if ((varUserPass == "") && (varUserName == ""))
{
errMsg.Add("Username", "Username cannot be blank");
errMsg.Add("Password", "Username cannot be blank");
}
else
{
if (varUserName == "")
{
errMsg.Add("Username", "Username cannot be blank");
}
if (varUserPass == "")
{
errMsg.Add("Password", "Password cannot be blank");
}
}
return errMsg;
}
}
You can then call it like that in your code: 然后可以在代码中这样调用它:
Login login = new Login();
var errMsg = login.LogMeIn();
