C# 怎么将数据存入txt中

Answer 1

给你个方法，传入参数就行。

#region 导出数据
/// <summary>
/// 导出数据
/// </summary>
/// <param name="FullFileName"></param>
/// <param name="TextAll"></param>
/// <returns></returns>
private bool TxtExport(string FullFileName, string TextAll)
{
if (!CreatFile(FullFileName))
{
return false;
}

StreamWriter sw = new StreamWriter(FullFileName, true, Encoding.Default); //该编码类型不会改变已有文件的编码类型
sw.WriteLine(TextAll);
sw.Close();
return true;
}
#endregion

#region 创建文件（文件存在则跳过）
/// <summary>
/// 创建文件（文件存在则跳过）
/// </summary>
/// <param name="FullFileName">带路径的文件名</param>
/// <returns></returns>
private bool CreatFile(string FullFileName)
{
if (File.Exists(FullFileName))
{
return true;
}
else
{
try
{
FileStream fs = new FileStream(FullFileName, FileMode.CreateNew);
fs.Close();
return true;
}
catch (Exception e)
{
MessageBox.Show(e.Message.ToString());
return false;
}
}
}

{

FileStream fs1 = new FileStream("E:\\TestTxt.txt", FileMode.Create, FileAccess.Write);//创建写入文件
StreamWriter sw = new StreamWriter(fs1);
sw.WriteLine("ABC");//开始写入值

sw.Close();
fs1.Close();

}

{
FileStream fs = new FileStream("E:\\TestTxt.txt", FileMode.Open, FileAccess.Write);
