(Mono C#) CSV Special Chars - Comma, Double-QuotesThe Chilkat CSV class/component automatically handles special characters which include double-quotes, and the delimiter character (comma or semicolon). The Chilkat CSV library/component/class is freeware. The downloads for .NET, C++, Perl, Java, Ruby, and Python contain all of the Chilkat classes, some of which are freeware and some of which require licensing.
// This example program loads a file (sample.csv) // that contains this content: // // year,color,country,food // 2001,red,France,cheese // 2005,blue,"United States",hamburger // 2008,green,Italy,pasta // 1998,orange,Japan,sushi // // The first row contains the column names. // This file is available at: // http://www.chilkatsoft.com/testData/sample.csv Chilkat.Csv csv = new Chilkat.Csv(); // Prior to loading the CSV file, indicate that the 1st row // should be treated as column names: csv.HasColumnNames = true; // Load the CSV records from the file: bool success; success = csv.LoadFile("sample.csv"); if (success != true) { Debug.WriteLine(csv.LastErrorText); return; } // A field may contain the delimiter character (in this case // the delimiter is a comma): // Change "cheese" to "cheese,baguette" // ("cheese" is at row=0, column=3 success = csv.SetCell(0,3,"cheese,baguette"); // A field may also contain double-quotes: // Change blue to shiny "metallic" blue success = csv.SetCell(1,1,"shiny \"metallic\" blue"); // Write the updated CSV to a string and display: string csvDoc; csvDoc = csv.SaveToString(); Debug.WriteLine(csvDoc); // Save the CSV to a file: success = csv.SaveFile("out.csv"); if (success != true) { Debug.WriteLine(csv.LastErrorText); } // The out.csv contains this: // year,color,country,food // 2001,red,France,"cheese,baguette" // 2005,"shiny ""metallic"" blue","United States",hamburger // 2008,green,Italy,pasta // 1998,orange,Japan,sush |
