c# - 解析以所需格式C#从.txt文件上传到内存的文本

这对C＃来说还很新……我想做的是从上传到内存的.txt文件中解析一堆文本到网页上。

这是.txt文件的样子

.RES B7=121
.RES C12=554
.RES VMAX=4.7μV

---

Again, it goes on like this for another 50 or so .RES'...I've successfully got it to parse, but not in the desired format...
Here's how I want it to look on the webpage

---

B7.........121
C12.........554
VMAX.........4.7μV

  全部隐藏在id =“ outpt” ...的隐藏面板中，当前设置为visible =“ false”
  
  


这是我在C＃页面中使用的代码

namespace Sdefault
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void btnUpld_Click(object sender, EventArgs e)
        {
            Stream theStream = file1.PostedFile.InputStream; //uploads .txt file     to memory for parse

            using (StreamReader sr = new StreamReader(theStream))
            {
                string tba;
                while ((tba = sr.ReadLine()) != null)
                {

                    string[] tmpArray = tba.Split(Convert.ToChar("=")); //Splits ".RES B7=121" to "B7"... but for some reason, It prints it as
                                                                        //".RES B7.RES C12.RES VMAX"... I would ultimately desire it to be printed as shown above




                    Response.Write(tmpArray[0].ToString());
                    var.Text = tba;
                    outpt.Visible = true;
                }

            }

        }
    }

}

我应该朝哪个方向发展？

最佳答案

// Open the file for reading
using (StreamReader reader = new StreamReader((Stream)file1.PostedFile.InputStream))
{
  // as long as we have content to read, continue reading
  while (reader.Peek() > 0)
  {
    // split the line by the equal sign. so, e.g. if:
    //   ReadLine() = .RES B7=121
    // then
    //   parts[0] = ".RES b7";
    //   parts[1] = "121";
    String[] parts = reader.ReadLine().split(new[]{ '=' });

    // Make the values a bit more bullet-proof (in cases where the line may
    // have not split correctly, or we won't have any content, we default
    // to a String.Empty)
    // We also Substring the left hand value to "skip past" the ".RES" portion.
    // Normally I would hard-code the 5 value, but I used ".RES ".Length to
    // outline what we're actually cutting out.
    String leftHand = parts.Length > 0 ? parts[0].Substring(".RES ".Length) : String.Empty;
    String rightHand = parts.Length > 1 ? parts[1] : String.Empty;

    // output will now contain the line you're looking for. Use it as you wish
    String output = String.Format("<label>{0}</label><input type=\"text\" value=\"{1}\" />", leftHand, rightHand);
  }

  // Don't forget to close the stream when you're done.
  reader.Close();
}
