I am using CSOM for creating new file. The file name contains specials characters.

The file name is !@@#$#%$%^^&^&(())(_+{}}.rar If I create file name as it is it gets fails or partially created

FileCreationInformation f_ObjInfo   =  new FileCreationInformation();
f_ObjInfo.ContentStream = new MemoryStream();
f_ObjInfo.Url           = f_Url+ "/"+"!@@#$#%$%^^&^&(())(_+{}}.rar"


How can I handle special characters wile file creation?


I also tried with


but not able to encode all characters properly.

Thanks in advance.

To support # and % you should use new ResourcePath API

fileResourcePath = ResourcePath.FromDecodedUrl(f_Url+ "/"+"!@@#$#%$%^^&^&(())(_+{}}.rar");
f_DestFolder.Files.AddUsingPath(fileResourcePath, new FileCollectionAddParameters(), new MemoryStream());
