直接ReadToEnd都读出来 然后Split(' ')变成数组 然后你就循环好了,每3个是一行数据,循环填充到DataTable里,绑定

[S314324153]

一行一行读再split 一次全读再split两次

[於黾]

哦,差点忘了 如果你文档里本来就是带换行的,而不是自动换行后变成这样 那么一次全读之后 先Replace("\r","").Replace("\n","")把换行都去掉,再Split

[exception92]

以0 分组； 新建包含三个 属性的类，第一个属性 默认为0； 遍历分组，转成类，添加到list集合； 绑定到dgv控件

[lgfcs]

注意：用split()后，你的string里面再也没有空格，\t等。所以无法得到带有空格的字符串；如果楼主目标数据都只是数字，可用放心使用split

[wind_cloud2011]

//新建一个datatable用于保存读入的数据  
DataTable dt = new DataTable();  
//给datatable添加三个列  
dt.Columns.Add("aa", typeof(String));  
dt.Columns.Add("bb", typeof(String));  
dt.Columns.Add("cc", typeof(String));  
//读入文件  
using (StreamReader reader = new StreamReader("1.txt", Encoding.Default))  
{  
    //循环读取所有行  
    while (!reader.EndOfStream)  
    {  
        //将每行数据，用-分割成3段  
        string[] data = reader.ReadLine().Split(' ');//每行数据之间有一个空格　  
        //新建一行，并将读出的数据分段，分别存入对应的列中，有几列建立几个  
        DataRow dr = dt.NewRow();  
        dr[0] = data[0];  
        dr[1] = data[1];  
        dr[2] = data[2];  
        //将这行数据加入到datatable中  
        dt.Rows.Add(dr);  
    }  
}  
//将datatable绑定到datagridview上显示结果  
this.dataGridView1.DataSource = dt;

双层循环 读到DataTable中 直接指定数据源 解决

[奔跑的猿人]

代码：
FileStream fs = new FileStream("..//..//..//test.txt", FileMode.Open);//打开文件
StreamReader sr = new StreamReader(fs);//读文件
string txt = sr.ReadToEnd().Replace("\r\n", "");//将换行符去除
string[] txtArray = txt.Split(' ');//分割
DataTable dt = new DataTable();
dt.Columns.Add("显示数据", typeof(string));//新增一列
int arrayLength = txtArray.Length / 3;//计算行数
int z = 0;
for (int i = 0; i < arrayLength; i++)
{
DataRow dataRow = dt.NewRow();
dataRow["显示数据"] = txtArray[z] + " " + txtArray[z + 1] + " " + txtArray[z + 2];
dt.Rows.Add(dataRow);
z = z + 3;
}
dgvShow.DataSource = dt;
dgvShow.Columns["显示数据"].Width = 300;//列宽

DataRow dataRow 最好在循环外定义，不然没循环一次都New一个对象，想想内存.

[wuyq11]

List<string> lst= new List<string>(); lst= File.ReadAllLines(inFilePath, Encoding.Unicode).ToList(); linq或循环分割
