C# 本地txt文件读取至comboBox下拉列表

在网上找了很多资料，最后通过调试，读取项目名称功能是实现了，具体的优化暂时没时间去弄

值得注意的是，页面在返回即刷新的时候要预处理清空下comboBox的值，否则会引起重复

 

this.combox.Items.Clear();

 

代码如下：

 

///

/// 从txt文件中得到项目名称，再显示到comboBox上 ///

private void ConvertTxtToDataSet() { string ReadLine; string[] array; string Path = @"E:/1.TXT"; StreamReader reader = new StreamReader(Path, System.Text.Encoding.GetEncoding("GB2312")); while (reader.Peek() >= 0) { try { ReadLine = reader.ReadLine(); if (ReadLine != "") { ReadLine = ReadLine.Replace("/"", ""); array = ReadLine.Split(','); if (array.Length == 0) { MessageBox.Show("您选择的导入数据类型有误，请重试！"); return; } this.comboxQcProName.Items.Add(array[0]); } } catch (Exception ex) { MessageBox.Show(ex.ToString()); } } }

 

期中TXT里面文件1.txt格式为：

                                         白细胞,"JEF",205.00,0.0351
                                         绿细胞,"JEF",7516.00,0.0382
                                         黑细胞,"JEF",1681.00,0.0675
                                         蓝细胞,"JEF",213.00,0.0563

结论：该函数自动读取文件txt一次读写一行文本，自动循环的读完所有内容
