将保存saveialog的文件名附加到该文件
||
我试图在要保存的文本文件的第一行中附加文件名。我该怎么做？这是一个代码。我找不到为stringbuilder追加实例实例的方法。
StringBuilder sb = new StringBuilder();
sb.AppendLine(\"BLAH BLAH\");
if (saveFile.ShowDialog() == DialogResult.OK)
{
//How to append file name at the beggining of the file to be saved?
File.WriteAllText(saveFile.FileName, sb.ToString());
}
没有找到相关结果

StringBuilder sb = new StringBuilder(); // Appending string to your StringBuilder string value. sb.AppendLine(\"BLAH BLAH\"); if (saveFile.ShowDialog() == DialogResult.OK) { // Keep the previous file text .. By inserting it in the begining of the // StringBuilder string value. sb.Insert(0, File.ReadAllText(saveFile.FileName) + Environment.NewLine); // Insert File Name in the begining of the StringBuilder string value. sb.Insert(0, saveFile.FileName + Environment.NewLine); File.WriteAllText(saveFile.FileName, sb.ToString()); }
