请不要要求工作的人免费快速回答".

您可以使用File.ReadAllLines，然后选择所需行的索引.

You can use File.ReadAllLines and then choose the index of the line you want.

您好，Jyotshnad，

是的，但是首先您可以阅读全文文件，然后获取特定的行值.

Hi Jyotshnad,

Ya its possible.But first you can read full text file and then to get particular line value.

// Namespace
using System.IO;  

    Private string ReadTextFile(int nReadLine)
    {
        // For Example nReadLine =3
        int nCount=0;
        string sOutput=sting.Empty;         
         using (StreamReader sr = new StreamReader("C:\\SampleFile.txt"))
            {
                string line;                                
                while ((line = sr.ReadLine()) != null)
                {
                   nCount++;
                   if(nCount==nReadLine) 
                     sOutput=line; 
                }
            }        
        return sOutput;
     }

我希望这段代码对您有用.

干杯:)

哦，抱歉

如果您对字符串非常熟悉，并且可以使用流阅读器完成所有操作
