Sw.WriteLine('This is the second line.') You can handle these using a When clause in a catch statement, as the following example shows. The file name is missing, or the file or directory is in use.ДЄn argument supplied to the method is invalid. The following table lists error codes that may be wrapped in an IOException. To convert the HResult value to a Win32 error code, you strip out the upper 16 bits of the 32-bit value. In the case of an IOException, you can get additional error information from the IOException.HResult property. Otherwise, because it is the base class of all other IO exceptions, the catch blocks of derived classes will not be evaluated. Note that, in your exception handling code, you should always handle the IOException last. The most likely exception to be thrown in this case is an IOException, although any other exception type could also be thrown. NET Core 2.1, validation checks for path correctness (for example, to ensure that invalid characters are not present in a path) have been removed, and the runtime throws an exception mapped from an operating system error code rather than from its own validation code. This means that it can be thrown by any I/O operation.Д«ecause IOException is the base class of the other exception types in the System.IO namespace, you should handle in a catch block after you've handled the other I/O-related exceptions. This means that, when calling I/O APIs, your code should be prepared to handle most or all of these exceptions, as shown in the following table: Exception typeДЄs the base class for exceptions in the System.IO namespace, IOException is also thrown for any error code that does not map to a predefined exception type. Exception handling in I/O operationsД«ecause of this reliance on the operating system, identical exception conditions (such as the directory not found error in our example) can result in an I/O method throwing any one of the entire class of I/O exceptions. However, it may also throw a FileNotFoundException. For example, because you are working with a directory rather than a file, you would expect that providing an invalid directory path to the DirectoryInfo constructor throws a DirectoryNotFoundException. As a result, unexpected exceptions can occur. However, the precise conditions under which the operating system returns particular error codes is often undocumented or poorly documented.

In most cases, it does this by directly translating the error code into its corresponding exception type it does not perform any special mapping of the error based on the context of the method call.ДЇor example, on the Windows operating system, a method call that returns an error code of ERROR_FILE_NOT_FOUND (or 0x02) maps to a FileNotFoundException, and an error code of ERROR_PATH_NOT_FOUND (or 0x03) maps to a DirectoryNotFoundException. The method then translates the error information, typically in the form of an error code, into a. When an I/O error occurs in code executed by the operating system, the operating system returns error information to the.

NET Framework wrap calls to the underlying operating system. NET Framework.)Д«ecause the file system is an operating system resource, I/O methods in both.

, which is thrown for applications running in limited trust that lack the necessary permissions on.

System.NotSupportedException, which is thrown for invalid colons in.

System.ArgumentException, which is thrown for invalid path characters on.

It is thrown for errors whose return codes from the operating system don't directly map to any other exception type.

System.IO.IOException, the base class of all System.IO exception types.

NET file system methods can throw the following exceptions: In addition to the exceptions that can be thrown in any method call (such as an OutOfMemoryException when a system is stressed or an NullReferenceException due to programmer error).
