C# C从目录中获取所有不带扩展名的文件名

我正在寻找一种方法来读取目录路径中的所有txt文件，而不将其扩展名放入数组中。我查看了path.getFileName，没有outExtension，但它只返回一个文件。我想要指定路径中的所有*.txt文件名

谢谢

类似于：

String[] fileNamesWithoutExtention = 
Directory.GetFiles(@"C:\", "*.txt")
.Select(fileName => Path.GetFileNameWithoutExtension(fileName))
.ToArray();

我们应该做到这一点

var filenames = Directory.GetFiles(myPath, "*.txt")
.Select(filename => Path.GetFileNameWithoutExtension(filename).Substring(1));

为注释中的规范添加的子字符串1

var files=from f in Directory.EnumerateFilesmyPath，*.txt 选择Path.getfilename withoutextensionf.Substring1；

只需将其转换为数组[]

   string targetDirectory = @"C:\...";

// Process the list of files found in the directory. 
   string[] fileEntries = Directory.GetFiles(targetDirectory,  "*.csv").Select(Path.GetFileNameWithoutExtension).Select(p => p.Substring(0)).ToArray();

   foreach (string fileName in fileEntries)
        {
          //Code
        }

最后我得到了解决方案。。。我希望它能起作用

另外一个要求是，我需要从所有文件名中删除第一个字符。我该怎么做？一次选择比两次选择更有效你的问题有点不清楚。filename.Substring0,1将只提供第一个字符。filename.Substring1将提供除第一个字符以外的所有内容。

   string targetDirectory = @"C:\...";

// Process the list of files found in the directory. 
   string[] fileEntries = Directory.GetFiles(targetDirectory,  "*.csv").Select(Path.GetFileNameWithoutExtension).Select(p => p.Substring(0)).ToArray();

   foreach (string fileName in fileEntries)
        {
          //Code
        }

public void getTestReportDocument(string reportid, string extenstype)
{
    try
    {
        string filesName = "";
        if (sqlConn.State == ConnectionState.Closed)
            sqlConn.Open();
        if(extenstype == ".pdf")
        {
            filesName = Path.GetTempFileName();
        }
        else
        {
            filesName = Path.GetTempFileName() + extenstype;
        }

        SqlCommand cmd = new SqlCommand("GetTestReportDocuments", sqlConn);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@ReportID", reportid);

        using (SqlDataReader dr = cmd.ExecuteReader(System.Data.CommandBehavior.Default))
        {
             while (dr.Read())
             {
                 int size = 1024 * 1024;
                 byte[] buffer = new byte[size];
                 int readBytes = 0;
                 int index = 0;
                 using (FileStream fs = new FileStream(filesName, FileMode.Create, FileAccess.Write, FileShare.None))
                 {
                     while ((readBytes = (int)dr.GetBytes(0, index, buffer, 0, size)) > 0)
                     {
                         fs.Write(buffer, 0, readBytes);
                         index += readBytes;
                     }
                 }
             }
        }
        Process prc = new Process();
        prc.StartInfo.FileName = filesName;
        prc.Start();
   }

   catch (Exception ex)
   {
       throw ex;
   }
   finally
   {
       //daDiagnosis.Dispose();
       //daDiagnosis = null;
   }
}
