想要以 Visual Studio 2013 中另一个解决方案的形式从文本框中访问数据？

Question

我有两个解决方案 TransferService 和 Sender。 TranferService 具有 WCF 服务和 IISHost 来托管该服务。在发件人解决方案中，我有 Windows 窗体应用程序。在该表单中，我使用按钮浏览和选择文件，使用文本框显示所选文件路径，使用另一个按钮（发送）通过 WCF 服务传输该文件。但我无法访问传输解决方案中的文本框值。它显示“当前上下文中不存在该名称”。
TransferService 代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace TransferService
{

// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "TransferService" in both code and config file together.
public class TransferService : ITransferService
{

    public File DownloadDocument()
    {
        File file = new File();
        String path = txtSelectFilePath.Text;
        file.Content = System.IO.File.ReadAllBytes(@path);
        //file.Name = "ImagingDevices.exe";

        return file;
    }
}
}

我在这条线上遇到错误

String path = txtSelectFilePath.Text;

form.cs 的代码

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Sender
{
public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Browse_Click(object sender, EventArgs e)
    {              
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            txtSelectFilePath.Text = openFileDialog1.FileName;

        }

    }

    private void Send_Click(object sender, EventArgs e)
    {
        TransferService.TransferServiceClient client = new TransferService.TransferServiceClient();
        TransferService.File file = client.DownloadDocument();
        System.IO.File.WriteAllBytes(@"C:\DownloadedFiles\" + file.Name, file.Content);
        MessageBox.Show(file.Name + " is downloaded");
    } 


}
}

ITransferService.cs 的代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;

namespace TransferService
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "ITransferService" in both code and config file together.
[ServiceContract]
public interface ITransferService
{
    [OperationContract]
    File DownloadDocument();
}

[DataContract]
public class File
{
    [DataMember]
    public string Name { get; set; }

    [DataMember]
    public byte[] Content { get; set; }

}
}

提前多谢了…………

Answer 1

然后为您的类创建一个构造函数，该构造函数以字符串形式接收路径，如下所示：

public class TransferService : ITransferService
{

    private string _path;
    public TransferService(string path) {
        _path  = path
    }

    public File DownloadDocument()
    {
        File file = new File();
        //String path = txtSelectFilePath.Text;
        file.Content = System.IO.File.ReadAllBytes(_path);
        //file.Name = "ImagingDevices.exe";

        return file;
    }
}

然后在 form.cs 上

 TransferService.TransferServiceClient client = new TransferService.TransferServiceClient(txtSelectFilePath.Text);
