在WPF中将搜索字符串与ILIST进行比较 [英] Comparing the Search String with the ILIST in WPF

问题描述

这是我第一次将WPF与LINQ一起使用
我正在编写以下代码来加载列表框

Hi,
This is the first time i am using WPF with LINQ
I am writing the below code to load the listbox

string usageIndicator = AppEnvironment.ToUpper() == "PROD" ? "P" : "T";

using (X12837DataContext dc = new X12837DataContext(_ediConnectionstring))
  
{
  
IList<tbl837SubmissionGroupData> submissionGroups = dc.tbl837SubmissionGroupDatas.Where(s => s.UsageIndicator == usageIndicator &&
                        (s.SelectClaimsByDate == "Y" || s.SelectClaimsNotSent == "Y")).OrderBy(g => g.SubmissionGroupName).ToList();
                    lstBoxSubmissionGroup.ItemsSource = submissionGroups;
                    lstBoxSubmissionGroup.DisplayMemberPath = "SubmissionGroupName";
                    ResponseText = string.Format("{0} submission groups listed.\n", submissionGroups.Count);
                }

其中tbl837SubmissionGroupData是包含所有属性的类，
SubmitGroups和submissionGroupName是属性.

现在的数据就像提交组有[0]，[1]，[2]，[3]
哪个内部变量包含变量...
[0] ==> id，groupname，groupid

所以我想检查所有列表[0] [1] [2] [3]来查找一个字符串，假设"mat"是整个列表中的唯一值并获取其索引.

例如我在[2]中找到了mat，然后我想返回2作为索引

怎么做.我在上面的代码之后编写了以下代码，但是现在没有用了，请您提出一种更好的方法或通过任何链接帮助我

where tbl837SubmissionGroupData is a class containing all the attributes ,
submissionGroups andsubmissionGroupName are the attributes.

now the data is like submissiongroups have [0],[1],[2],[3]
which internall contains variables...
[0] ==> id, groupname,groupid

so i want to check all the list [0][1][2][3] data to find a string suppose "mat"which is a unique value in the entire list and get its index.

for example i found mat in [2] then i want to return 2 as index

how to do that. i wrote the following code after the above code but no use i am getting nowher could u please suggest a better approach or help me with any link

IEnumerable items = lstBoxSubmissionGroup.Items; 
                foreach (object obj in items) 
                {
                    string val = obj as string;
                    if ((!string.IsNullOrEmpty(val)) && val.Contains(searchString)) 
                    {
                        int id = lstBoxSubmissionGroup.Items.IndexOf(obj);                       
                    } 
                } 

推荐答案

看看是否有帮助:

(假设"MAT"为组名)

Hi,

See if this helps:

(Assuming "MAT" is a groupname)

IEnumerable items = lstBoxSubmissionGroup.Items;

            foreach (var item in lstBoxSubmissionGroup.Where(Source => Source.groupName== "XYZ"))
            {
//Index in the main collection
            Console.WriteLine(submissionGroups.IndexOf(item));
//Index in the Subset
            Console.WriteLine(lstBoxSubmissionGroup.IndexOf(item));
            }
