在C＃中将文件下载到新创建的目录

Question

我正在动态创建目录，我想将文件下载到新创建的目录：

// The code to create the directory based on revision number and original name
System.IO.Directory.CreateDirectory(@"C:\Users\bob\Desktop\Hello\Files\" + "v" + fileInfo.RevisionNumber + "_" + fileInfo.OriginalName);

// This method downloads files and takes 4 parameters. 
// The only one that really matters is the second one, targetFolder, 
// which is a String value. Any idea on how I can download the files 
// to the newly created directory (above) using the method below?
ecm.RetrieveFile(fileInfo.ID, targetFolder, recreateDirectoryStructureFlag, overwriteWithoutPromptFlag);

Answer 1

var targetFolder = @"C:\Users\bob\Desktop\Hello\Files\" + "v" + fileInfo.RevisionNumber + "_" + fileInfo.OriginalName;
System.IO.Directory.CreateDirectory(targetFolder);
ecm.RetrieveFile(fileInfo.ID, targetFolder, recreateDirectoryStructureFlag, overwriteWithoutPromptFlag);

Answer 2

将您传递的相同字符串传递给CreateDirectory 将字符串放在单独的变量中并将变量传递给两个函数可能很有用。

Answer 3

CreateDirectory会返回DirectoryInfo个对象。如果存储了返回的对象，则可以将newDirectory.FullPath传递给下载功能。

Answer 4

string targetFolder= System.IO.Directory.CreateDirectory(@"C:\Users\bob\Desktop\Hello\Files\" + "v" + fileInfo.RevisionNumber + "_" + fileInfo.OriginalName).FullName;

ecm.RetrieveFile(fileInfo.ID, targetFolder, recreateDirectoryStructureFlag, overwriteWithoutPromptFlag);

Answer 5

我了解到DirectoryInfo对象具有FullName方法，该方法返回完整路径。我用这种方法来获取路径。

感谢大家的帮助。
