打开文件

[zqsntws]

我在datagrid里有一列是超链列，点击该列会弹出“打开，保存，取消，信息”的WINDOW提示框，用户可以把该文件保存到本地，也可以直接打开该文件，能否把打开按钮灰掉？或是隐藏该按钮？

这个方法可以读出别的类型的文件吗？比如word文件的内容，或是pdf的文件？

不可以，除非你用StreamWriter自己将文件流写到本地，而不是用IE的下载功能。

---------------------------------------
using System;
using System.IO;

class Test
{
public static void Main()
{
try
{
// Create an instance of StreamReader to read from a file.
// The using statement also closes the StreamReader.
using (StreamReader sr = new StreamReader("TestFile.txt"))
{
String line;
// Read and display lines from the file until the end of
// the file is reached.
while ((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
}
catch (Exception e)
{
// Let the user know what went wrong.
Console.WriteLine("The file could not be read:");
Console.WriteLine(e.Message);
}
}
}

--------------------------------------------------------

using System;
using System.IO;

class Test
{
public static void Main()
{
// Create an instance of StreamWriter to write text to a file.
// The using statement also closes the StreamWriter.
using (StreamWriter sw = new StreamWriter("TestFile.txt"))
{
// Add some text to the file.
sw.Write("This is the ");
sw.WriteLine("header for the file.");
sw.WriteLine("-------------------");
// Arbitrary objects can also be written to the file.
sw.Write("The date is: ");
sw.WriteLine(DateTime.Now);
}
}
}

我还想让用户自己选择保存的路径，这个怎么实现？

怎么让用户选择路径，然后调用我的过程把选择的文件保存到指定目录下？
