[英]C# load JSON files to Listbox by using datasource from a listbox
I saved JSON files from a local folder.我从本地文件夹中保存了 JSON 文件。 Please see below:
请看下面:
Ivan Deaking.json伊万·迪金.json
{
"FirstName": "Ivan",
"LastName": "Deakin",
"Email": "ivan.deakin",
"TeamName": "Ivan Deakin",
"Password": "ivan12345",
"IsActive": "Yes",
"UserId": 5
}
And here's my code below:下面是我的代码:
private void ShowListView()
{
//listBoxUsers.Items.Clear();
var dir = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
var outputDir = Path.Combine(dir, "Output");
foreach (var file in Directory.GetFiles(outputDir, "*.json"))
{
var text = File.ReadAllText(file);
var model = JsonConvert.DeserializeObject<UserAccount>(text);
listBoxUsers.Items.Add(model);
}
}
Currently, this code is using Items.Add to load the JSON file to a listview.目前,此代码使用 Items.Add 将 JSON 文件加载到列表视图。 What I am trying to achieve is to use datasource instead of Items.Add to fill the listbox.
我想要实现的是使用数据源而不是 Items.Add 来填充列表框。
Please see code below:请看下面的代码:
listBoxUsers.DataSource = model;
But it doesn't allow me and it gives me an error 'Complex DataBinding accepts as a datasource either an IList or an IListSource .但它不允许我,它给了我一个错误“复杂 DataBinding 接受 IList 或 IListSource 作为数据源。 I am not sure though if I need to convert the "model" first into list of strings.
我不确定是否需要先将“模型”转换为字符串列表。 Can anyone help me with this?
谁能帮我这个?
Your function should be like this:你的功能应该是这样的:
private void ShowListView()
{
List<UserAccount> userAcounts = new List<UserAccount>();
//listBoxUsers.Items.Clear();
var dir = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);
var outputDir = Path.Combine(dir, "Output");
foreach (var file in Directory.GetFiles(outputDir, "*.json"))
{
var text = File.ReadAllText(file);
var model = JsonConvert.DeserializeObject<UserAccount>(text);
userAcounts.Add(model);
}
listBoxUsers.DataSource = userAcounts;
}
