如何在现有文本文件中写入和追加?以下是一个示例
public static void WriteBackgroundSetting(string currentBackground)
{
const string fileName = "RecipeHub.txt";
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if(myIsolatedStorage.FileExists(fileName))
myIsolatedStorage.DeleteFile(fileName);
var stream = myIsolatedStorage.CreateFile(fileName);
using (StreamWriter isoStream = new StreamWriter(stream))
{
isoStream.WriteLine(currentBackground);
}
}
}
。创建StreamWriter,文档将告诉您如何设置附加模式。StreamWriter不够,您无法写入应用程序资源。在修改文件之前,您必须将其复制到独立存储中
