我想通过csv上传一系列客户端信息,我在eginning中遇到了一些问题,但是我之前的文章已经回答了,所以我能够开始读取数据它只读取第一行。只是想知道如果有人有任何想法。我已经包括以下csv文件只读第一行
private void btnUpload_Click(object sender, EventArgs e)
{
//Browse for file
OpenFileDialog ofd = new OpenFileDialog();
//Only show .csv files
ofd.Filter = "Microsoft Office Excel Comma Separated Values File|*.csv";
DialogResult result = ofd.ShowDialog();
//If the user selects a valid file
if (result == DialogResult.OK)
{
//File is delimited by a comma
char[] laClientDelim = { ',' };
//New object for string manipulation
objStringManipulation = new StringManipulation();
// Parse the csv file
List<string[]> lsClientList = objStringManipulation.parseCSV(ofd.FileName, laClientDelim);
foreach (string[] laClient in lsClientList)
{
//Create new object for manipulating the database
objSqlCommands = new SqlCommands("Client", "ClientName");
string[] records = File.ReadAllLines(ofd.FileName); // read the file completely line by line
char splitChar = ',';
int splitCharCount = 0;
int k = 0;
string[] fields = records[k].Split(splitChar); // reads all the single values per line. 'splitChar' should be the delimiter.
splitCharCount++;
if (splitCharCount >= 4 && splitCharCount <= 10)
{
var stuff = from l in File.ReadLines(ofd.FileName)
let x = l.Split(new[] { ',', ' ' }, StringSplitOptions.RemoveEmptyEntries)
.Skip(1)
.Select(s => char.Parse(s))
select new
{
Client = x,
ClientName = x
};
}
//Inserts the client info into datbase
objSqlCommands.sqlCommandInsertorUpdate("INSERT", records[k]);//laClient[0]);
k++;
//Refreshs the Client table on display from the
this.clientTableAdapter.Fill(this.kIIDImplementationCalcDataSet.Client);
//MAKE SURE TO ONLY ADD IN CLIENT AND CLIENT NAME
//update the view
dgvClientlst.Update() ;
}
}
}
我想你理解一个变量的范围。变量K在for循环中定义,因此在每个循环中一次又一次地实例化为0。在你的循环之外声明K。 – Guanxi
