您可以使用此代码：
public ActionResult Log()

var fileContents = System.IO.File.ReadAllText(Server.MapPath("~/Views/Builder/TestLogger.txt"));
return Content(fileContents);

You can use ContentResult, it is used to return text content from Controller Actions.
您可以使用ContentResult，它用于从控制器操作返回文本内容。
[HttpGet]
public ActionResult Log() {
try {
string content = string.Empty;
using (var stream = new StreamReader(Server.MapPath("~/Views/Builder/TestLogger.txt"))) {
content = stream.ReadToEnd();
}
return Content(content);
}
catch (Exception ex) {
return Content("Something ");
}
}

Based on your comments to other answers, it would appear that the log file you're attempting to use is currently locked down by the server. It's likely opening and writing to the log file because you've initiated a request that is getting logged, so you're blocking yourself from reading it.
根据您对其他答案的评论，您尝试使用的日志文件目前似乎已被服务器锁定。它可能会打开并写入日志文件，因为您发起了一个正在记录的请求，因此您阻止了自己阅读它。
Assuming you're using a FileAppender, setting appender.LockingModel = FileAppender.MinimalLockwhen the logger is instantiated should allow the file to be accessed when nothing is being logged as opposed to the log4net process maintaining its lock while it is running.
假设您正在使用FileAppender,appender.LockingModel = FileAppender.MinimalLock实例化记录器时的设置应该允许在没有记录任何内容时访问文件，而不是 log4net 进程在运行时保持其锁定。
This can also be set in the configuration if all the properties are set pre-runtime:
如果所有属性都在运行前设置，也可以在配置中设置：
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
