[英]How can I use variable from a private method in another private method ? C# ASPX
So I've got a class with private method and I want to use a variable from one method to another one.所以我有一个带有私有方法的类,我想使用一个变量从一个方法到另一个方法。 I don't know how and where to start.
我不知道如何以及从哪里开始。 Should I use get and set or a creat a full public method, I don't know.
我应该使用 get 和 set 还是创建一个完整的公共方法,我不知道。
Here is the first method and I want to use the variable "prixTotal"这是第一种方法,我想使用变量“prixTotal”
private string RecupPrixTransaction(XmlDocument doc)
{
XmlNodeList nl = null;
XmlNode nodeDevise = null;
string data = string.Empty;
string devise = string.Empty;
decimal acompteTotal = 0;
decimal prixTotal = 0;
if (doc == null)
return (data);
nodeDevise = doc.SelectSingleNode("/Caddie/GroupesProduits/GroupeProduit[@IdGroupe='" + this.guid + "']/Devise");
if (nodeDevise == null)
return (data);
devise = nodeDevise.InnerText;
nl = doc.SelectNodes("/Caddie/GroupesProduits/GroupeProduit[@IdGroupe='" + this.guid + "']/Produits/Produit");
if (nl == null)
return (data);
try
{
foreach (XmlNode nd in nl)
{
prixTotal += decimal.Parse(nd["PrixTotal"].InnerText, System.Globalization.CultureInfo.InvariantCulture.NumberFormat);
acompteTotal += decimal.Parse(nd["AcompteTotal"].InnerText, System.Globalization.CultureInfo.InvariantCulture.NumberFormat);
}
data += "Prix total de la transaction: <strong>" + prixTotal + "</strong> " + devise + "<br />";
data += "Acompte total payé: <strong>" + acompteTotal + "</strong> " + devise + "<br />";
}
catch (Exception)
{
data += "Prix/acompte invalide.<br />";
}
return (data);
}
And here it's the method where I want to use the variable "prixTotal"这是我想使用变量“prixTotal”的方法
private void AffTransa(string id, SqlConnection sqlConnect)
{
SqlDataReader reader = null;
decimal recapPrixTotal = RecupPrixTransaction(prixTotal);
reader = Database.ExecuteReader(EnumConstant.SqlLecture + "SELECT * FROM transactionfin WHERE IdTransactionFin='" + id + "'", sqlConnect);
if (reader.Read())
{
this.lTransa.Text = "<h2>Détail de la transaction " + id + "</h2><br />";
this.lTransa.Text += "Date de la transaction: <b>" + reader["TransactionFinDate"] + "</b><br />";
this.date = reader["TransactionFinDate"].ToString();
this.lTransa.Text += "Solution de paiement: <b>" + MyRegex.ReplacePaiementSol(reader["PaiementSolution_IdPaiementSolution"].ToString()) + "</b><br />";
this.lTransa.Text += "{[{-}]}Mode: <b>" + MyRegex.ReplaceMode(reader["TransactionFinMode"].ToString()) + "</b><br />";
this.lTransa.Text += "Etat: <b>" + MyRegex.ReplaceEtat(reader["TransactionFinEtat"].ToString()) + "</b><br />";
if (reader["TransactionFinUrlRetour"].ToString() != " ")
this.lTransa.Text += "Url de retour: <a href=\"" + reader["TransactionFinUrlRetour"].ToString() + "\">" + MyRegex.ReplaceUrlRetour(reader["TransactionFinUrlRetour"].ToString()) + "</a><br />";
this.lTransa.Text += "<br /><br />Id Transaction: <b>" + reader["TransactionFinIdTransaction"] + "</b><br />";
this.lTransa.Text += "Guid: <b>" + reader["TransactionFinGuidGroupe"].ToString() + "</b><br />";
this.guid = reader["TransactionFinGuidGroupe"].ToString();
this.lTransa.Text += "Id action contact: <b>" + reader["ActionContact_IdActionContact"] + "</b><br />";
this.lTransa.Text += "Id vente entete: <b>" + reader["VenteEntete_IdVenteEntete"] + "</b><br />";
if (reader["TransactionFinDetail"] != null && reader["TransactionFinDetail"].ToString() != string.Empty)
{
this.tbTransa.Visible = true;
this.tbTransa.Text = XmlParsing.IndentXml(reader["TransactionFinDetail"].ToString());
this.lRecap.Text += "Recapitulatif de la Transaction : " ;
this.recapTransa.Visible = true;
this.recapTransa.Text += "#Fournisseur" + "\n" +
"#Internaute" + "\n" +
"#Montants" + "\n" + recapPrixTotal +
"#Produits" + "\n" +
"#Suppléments" + "\n";
}
}
reader.Close();
}
I tried to call the method like this but this doesn't work我试图像这样调用方法,但这不起作用
decimal recapPrixTotal = RecupPrixTransaction(prixTotal);
EDIT :编辑 :
At the top of the class i've put the variable "prixTotal" like this在课程的顶部,我把变量“prixTotal”像这样
public partial class SeeDetail : System.Web.UI.Page
{
private decimal prixTotal = 0;
...
}
I've removed it from the method RecupPrixTransaction Andin the AffTransa method, i call it like this我已经从 RecupPrixTransaction 方法中删除了它,并且在 AffTransa 方法中,我这样称呼它
decimal recapPrixTotal = prixTotal;
In the method RecupPrixTransaction the result of "prixTotal" is the good one But in the AffTransa method the number is always 0在 RecupPrixTransaction 方法中,“prixTotal”的结果是好的,但在 AffTransa 方法中,数字始终为 0
Thank you for your help ;)感谢您的帮助 ;)
In this way its, impossible.以这种方式其,不可能。 Now
prixTotal
is in method scope and its inaccessible from outside.现在
prixTotal
处于方法范围内并且无法从外部访问。 But you can move decimal prixTotal = 0;
但是你可以移动
decimal prixTotal = 0;
to class scope and then this variable will be accessible from both methods.到类作用域,然后可以从这两种方法访问此变量。
Class A
{
private decimal prixTotal = 0;
private void Method A ....
}
I tried to call the method like this but this doesn't work decimal recapPrixTotal = RecupPrixTransaction(prixTotal);
我试图像这样调用该方法,但这不起作用十进制 recapPrixTotal = RecupPrixTransaction(prixTotal);
RecupPrixTransaction
is of type String
RecupPrixTransaction
的返回类型是String
类型RecupPrixTransaction
is of type XmlDocument
and not decimal
RecupPrixTransaction
接受的参数是XmlDocument
类型而不是decimal
To Solve:解决:
private decimal prixTotal { get; set; }
private decimal prixTotal { get; set; }
private decimal prixTotal { get; set; }
private decimal prixTotal { get; set; }
at Class scope private decimal prixTotal { get; set; }
在类范围private string RecupPrixTransaction(XmlDocument doc) { prixTotal =0; ... }
private void AffTransa(string id, SqlConnection sqlConnect) { decimal recapPrixTotal= prixTotal; ... }
I can't see any way this will work.我看不出这有什么办法。
You are calling你在打电话
private string RecupPrixTransaction(XmlDocument doc)
which to me suggests the method is returning a string and passing a XmlDocument
对我来说,这表明该方法正在返回一个字符串并传递一个
XmlDocument
but what you are passing is但你正在传递的是
decimal recapPrixTotal = RecupPrixTransaction(prixTotal);
Where it looks like you are wanting a decimal
and passing an (to us at least) variable called prixTotal
看起来您想要一个
decimal
并传递一个(至少给我们)名为prixTotal
变量
If you want it to return a decimal
, I suggest changing the return type of the method, assuming that you ARE passing it an XmlDocument
.如果您希望它返回一个
decimal
,我建议更改该方法的返回类型,假设您正在向它传递一个XmlDocument
。
If they are in the same class, I don't see why the above would not hit the method.如果他们在同一个班级,我不明白为什么上述不会命中该方法。
