将数据从2d数组传递到dataGrid wpf C＃

I have an array:

我有一个数组:

   string Companies[,] = new string[100,7];

How can I put it to a dataGrid? I can't find any answear which works and I don't know where to start. I'm new to WPF, so can someone explain it to me, please?

我怎样才能把它放到dataGrid中?我找不到任何有效的衣服,我不知道从哪里开始。我是WPF的新手,有人可以向我解释一下吗?

Please use ItemsSource to assign data collections. I suggest you to read about MVVM implementation for WPF. But to start...

请使用ItemsSource分配数据集合。我建议你阅读WPF的MVVM实现。但要开始......

Create a class that implements INotifyPropertyChanged interface

创建一个实现INotifyPropertyChanged接口的类

public class Employer : INotifyPropertyChanged
{  
    private string nameField;
    public string Name {
        get { return nameField; }
        set {
            nameField= value;
            if (PropertyChanged != null) {
                PropertyChanged(this, new PropertyChangedEventArgs("Name"));
            }
        }
    }

    private int idField;
    public int Id {
        get { return idField; }
        set {
            idField= value;
            if (PropertyChanged != null) {
                PropertyChanged(this, new PropertyChangedEventArgs("Id"));
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

Create a property

创建一个属性

private ObservableCollection<Employer> employersField;
public ObservableCollection<Employer> Employers
{
        get { return employersField; }
    set {
        employersField= value;
        if (PropertyChanged != null) {
            PropertyChanged(this, new PropertyChangedEventArgs("Employers"));
        }
    }
}

Now let's say in a constructor you do

现在让我们说你做的构造函数

 Employers = new ObservableCollection<Employer> {
        new Employer {
            Id = 0,
            Name = "Mike"
        },
        new Employer {
            Id = 1,
            Name = "Dave"
        }
    }

Let's assume that you don't have view class so all your properties in a xaml related cs file. So you need to bind the DataContext property of your dataGrid to your class and after assign ItemsSource to your property

假设您没有视图类,因此xaml相关的cs文件中的所有属性都是如此。因此,在将ItemsSource分配给属性之后,需要将dataGrid的DataContext属性绑定到类

<DataGrid DataContext = {Binding ElementName=YourControlName}  ItemsSource="{Binding Employers}">
 your content
</DataGrid >

YourControlName is a userControl name in xaml!

YourControlName是xaml中的userControl名称!

<UserControl  x:Name="YourControlName" >
all stuff
</UserControl>

Look, this is a vary short overview, because I didn't show you how to bind your class properties to dataGrid columns and also how to bind selectedItem property to your property. But you can find many examples at * as well as on the Internet. I just showed how to start and how things work in WPF

看,这是一个不同的简短概述,因为我没有向您展示如何将类属性绑定到dataGrid列,以及如何将selectedItem属性绑定到您的属性。但是你可以在*和Internet上找到很多例子。我刚刚展示了如何在WPF中启动以及如何工作

Constructor List of objects as below use it

构造函数下面的对象列表使用它

class ViewModel
{
    public string[,] Companies
    {
        get;
        set;
    }
    public List<Example> Values
    {
        get;
        set;
    }
    public ViewModel()
    {
        Companies = new string[2, 2] { { "sjhbfsjh", "jshbvjs" }, {"vsmvs", "nm vmdz" } };
        Values = new List<Example>();
        for (int i = 0; i < 2; i++)
        {
            Example ee = new Example();
            ee.A = Companies[i, 0];
            ee.B = Companies[i, 1];
            Values.Add(ee);
        }
    }
}
public class Example
{
    public string A
    {
        get;
        set;
    }
    public string B
    {
        get;
        set;
    }
}

Then in your Xmal you can do as below

然后在您的Xmal中,您可以执行以下操作

<DataGrid ItemsSource="{Binding Path=Values}"></DataGrid>

Set the data context in Xmal.cs

在Xmal.cs中设置数据上下文

DataContext = new ViewModel();
