passing array via query string
提问by SHAKEEL HUSSAIN
I am passing a javascript array via Request.QueryString["cityID"].ToString(), but it shows me an error of "invalid arguments":
我正在通过 传递一个 javascript 数组Request.QueryString["cityID"].ToString()，但它向我显示了“无效参数”的错误：
blObj.addOfficeOnlyDiffrent(Request.QueryString["cityID"].ToString(),
Request.QueryString["selectTxtOfficeAr"].ToString());
The method declaration looks like:
方法声明如下所示：
public string addOfficeOnlyDiffrent(string[] cityID, string selectTxtOfficeAr) { }

Your method addOfficeOnlyDiffrentis expecting a string array arguement in cityIDwhereas you are passing a single stringtype object to your method in call. I believe your cityIDis a single string so you can remove the array from the method declaration. In your method call.
您的方法addOfficeOnlyDiffrent需要一个字符串数组参数，cityID而您string在调用中将单个类型对象传递给您的方法。我相信您cityID是一个字符串，因此您可以从方法声明中删除该数组。在你的方法调用中。
Request.QueryString["cityID"].ToString()
the above represents a single string, not a string array.
以上表示单个字符串，而不是字符串数组。
If your query string contains a string array, then values are probably in string representation, separated by some character, for example ,. To pass that string to the method, you can call string.Splitto split the string to get an array.
如果您的查询字符串包含字符串数组，则值可能采用字符串表示形式，由某些字符分隔，例如,. 要将该字符串传递给该方法，您可以调用string.Split拆分字符串以获取数组。
EDIT: From your comment, that your query string contains:
编辑：根据您的评论，您的查询字符串包含：
Request.QueryString["cityID"].ToString() (123456,654311,987654)
You can do the following.
您可以执行以下操作。
string str = Request.QueryString["cityID"].ToString();
string[] array = str.Trim('(',')').Split(',');
blObj.addOfficeOnlyDiffrent(array,
Request.QueryString["selectTxtOfficeAr"].ToString());

If your query string parameter value looks like: "123456,654311,987654"
如果您的查询字符串参数值类似于：“123456,654311,987654”
string[] ids = Request.QueryString["cityID"]
.Split( new[] {","}, StringSplitOptions.RemoveEmptyEntries );

try this it's so simple.
试试这个就这么简单。
string city = Request.QueryString["cityID"];
string[] cityID =city.Split(new char[] {','},StringSplitOptions.RemoveEmptyEntries);
You get string like this "123456,654311,987654" in city. You get array in cityID.
你会在city 中得到这样的字符串 "123456,654311,987654" 。您在 cityID 中获得数组。
