FileInfo.MoveTo() vs File.Move()
FileInfo.MoveTo() vs File.Move()
提问于 2010-04-29 05:32:44
这两种移动文件的方法有什么不同吗？
System.IO.FileInfo f = new System.IO.FileInfo(@"c:\foo.txt");
f.MoveTo(@"c:\bar.txt");
//vs
System.IO.File.Move(@"c:\foo.txt", @"c:\bar.txt");回答 2

通过RedGate反射器：
File.Move()
public static void Move(string sourceFileName, string destFileName)
{
if ((sourceFileName == null) || (destFileName == null))
{
throw new ArgumentNullException((sourceFileName == null) ? "sourceFileName" : "destFileName", Environment.GetResourceString("ArgumentNull_FileName"));
}
if ((sourceFileName.Length == 0) || (destFileName.Length == 0))
{
throw new ArgumentException(Environment.GetResourceString("Argument_EmptyFileName"), (sourceFileName.Length == 0) ? "sourceFileName" : "destFileName");
}
string fullPathInternal = Path.GetFullPathInternal(sourceFileName);
new FileIOPermission(FileIOPermissionAccess.Write | FileIOPermissionAccess.Read, new string[] { fullPathInternal }, false, false).Demand();
string dst = Path.GetFullPathInternal(destFileName);
new FileIOPermission(FileIOPermissionAccess.Write, new string[] { dst }, false, false).Demand();
if (!InternalExists(fullPathInternal))
{
__Error.WinIOError(2, fullPathInternal);
}
if (!Win32Native.MoveFile(fullPathInternal, dst))
{
__Error.WinIOError();
}
}和FileInfo.MoveTo()
public void MoveTo(string destFileName)
{
if (destFileName == null)
{
throw new ArgumentNullException("destFileName");
}
if (destFileName.Length == 0)
{
throw new ArgumentException(Environment.GetResourceString("Argument_EmptyFileName"), "destFileName");
}
new FileIOPermission(FileIOPermissionAccess.Write | FileIOPermissionAccess.Read, new string[] { base.FullPath }, false, false).Demand();
string fullPathInternal = Path.GetFullPathInternal(destFileName);
new FileIOPermission(FileIOPermissionAccess.Write, new string[] { fullPathInternal }, false, false).Demand();
if (!Win32Native.MoveFile(base.FullPath, fullPathInternal))
{
__Error.WinIOError();
}
base.FullPath = fullPathInternal;
base.OriginalPath = destFileName;
this._name = Path.GetFileName(fullPathInternal);
base._dataInitialised = -1;

我能看到的唯一显著区别是File.Move是静态的，而FileInfo.MoveTo不是。
除此之外，它们运行的代码大致相同。
