有人可以推薦一個CSV到Html Table Generator嗎？

Question

我需要解析一個非常簡單的csv文件，它代表7列和3行。是否有任何內置的.Net來做到這一點，或者我應該手動嗎？

Answer 1

原來，這工作：（好吧， '這' 是一個近似值）

protected void Page_Load(object sender, EventArgs e) 
{ 
    List<List<string>> data = GetListFromCsv(this.DataFile); 

    Table table = GetHtmlTable(data); 

    this.plcDataTable.Controls.Add(table); 
} 

// get list of 'rows' (event though each row is just a list of strings) 
public static List<List<string>> GetListFromCsv(string file) 
{ 
    String[] csvData = File.ReadAllLines(file); 

    List<string> rowList = new List<string>(); 

    if (csvData.Length == 0) 
    { 
     throw new Exception("CSV File Appears to be Empty"); 
    } 

    var rows = (from r in csvData 
       select r.Split(',').ToList() 
       ).ToList(); 

    return rows; 

} 

private Table GetHtmlTable(List<List<string>> dataTable) 
{ 
    List<TableRow> rows = new List<TableRow>(); 

    rows.AddRange(GetListOfRows(dataTable)); 

    Table table = new Table(); 
    table.Rows.AddRange(rows.ToArray()); 

    return table; 
} 

// convert the 'rows' to real rows. 
public static IEnumerable<TableRow> GetListOfRows(List<List<string>> table) 
{ 
    var rows = new List<TableRow>(); 

    foreach (var row in table 
    { 
     rows.Add(GetTableRow(row)); 
    } 

    return rows; 
} 

private static TableRow GetTableRow(List<string> rows) 
{ 
    TableRow row = new TableRow(); 

    row.Cells.Add(GetColumnOneCell(rows)); 
    row.Cells.AddRange(GetValueCells(rows).ToArray()); 

    return row; 
}

使用類似FileHelpers library的文件加載文件並將其轉換爲數據表，並使用中繼器以所需的html格式發送行。

怎麼樣：

public static DataTable csvToDataTable(string file, bool isRowOneHeader) 
{ 

DataTable csvDataTable = new DataTable(); 

//no try/catch - add these in yourselfs or let exception happen 
String[] csvData = File.ReadAllLines(HttpContext.Current.Server.MapPath(file)); 

//if no data in file ‘manually’ throw an exception 
if (csvData.Length == 0) 
{ 
    throw new Exception(」CSV File Appears to be Empty」); 
} 

String[] headings = csvData[0].Split(','); 
int index = 0; //will be zero or one depending on isRowOneHeader 

if(isRowOneHeader) //if first record lists headers 
{ 
    index = 1; //so we won’t take headings as data 

    //for each heading 
    for(int i = 0; i < headings.Length; i++) 
    { 
     //replace spaces with underscores for column names 
     headings[i] = headings[i].Replace(」 「, 「_」); 

     //add a column for each heading 
     csvDataTable.Columns.Add(headings[i], typeof(string)); 
    } 
} 
else //if no headers just go for col1, col2 etc. 
{ 
    for (int i = 0; i < headings.Length; i++) 
    { 
     //create arbitary column names 
     csvDataTable.Columns.Add(」col」+(i+1).ToString(), typeof(string)); 
    } 
} 

//populate the DataTable 
for (int i = index; i < csvData.Length; i++) 
{ 
    //create new rows 
    DataRow row = csvDataTable.NewRow(); 

    for (int j = 0; j < headings.Length; j++) 
    { 
     //fill them 
     row[j] = csvData[i].Split(’,')[j]; 
    } 

    //add rows to over DataTable 
    csvDataTable.Rows.Add(row); 
} 

//return the CSV DataTable 
return csvDataTable; 

}

的PowerShell：

ps> import-csv foo.csv | convertto-html foo.html
