streamreader读出来的文件的饿内容为空

[蓝色水]

StreamReader din = File.OpenText("b.txt");

string strall=null;
string str=null;
while((str = din.ReadLine()) != null)
{
strall = str + ",";

}

userAccount = strall;

[jiatong1981]

StreamReader din = File.OpenText(@"d:\b.txt");
string userAccount;
string strall = null;
string str = null;
while ((str = din.ReadLine()) != null)
{
strall += str + ",";

}

userAccount = strall;

[hooo]

while((str = din.ReadLine()) != null)
{
strall = strall + str + ","; //改这句增加一个strall 不然就只会显示最后一行

}

string strall=null，设置成静态看看

把你的代码贴出来

StreamReader din = File.OpenText(@"d:\b.txt"); //估计你的问题在这里,看看你的b.txt的文件路径怎么写的
string userAccount; 
string strall = null; 
string str = null; 
while ((str = din.ReadLine()) != null) 
{ 
   strall += str + ","; 

} 
userAccount = strall;

[liurenfu]

StreamReader MyReader=new StreamReader("b.txt",System.Text.Encoding.Default);
this.textBox1.Text=MyReader.ReadToEnd();

[jiatong1981]

#region Test
StreamReader din = File.OpenText(@"d:\b.txt"); //估计你的问题在这里,看看你的b.txt的文件路径怎么写的
string userAccount; 
string strall = null; 
string str = null; 
while ((str = din.ReadLine()) != null) 
{ 
   strall += str + ","; 

} 
userAccount = strall;
#endregion

同级目录同楼上 StreamReader din = File.OpenText(@"d:\b.txt");
或者在config里面加上路径

liurenfu 感谢，的确是字符集的问题，加了System.Text.Encoding.Default就解决了，thx
