解决方案

可以使用 FileHelpers开源库 或者参考下面代码：

最简单的方法可能是使用String.split。

例如：

String[] values = myString.Split(',');
myObject.StringField = values[0];
myObject.IntField = Int32.Parse(values[1]);

c# 导入CSV文件：

public static IList<IList<string>> Parse(string content)
{
    IList<IList<string>> records = new List<IList<string>>();

    StringReader stringReader = new StringReader(content);

    bool inQoutedString = false;
    IList<string> record = new List<string>();
    StringBuilder fieldBuilder = new StringBuilder();
    while (stringReader.Peek() != -1)
    {
        char readChar = (char)stringReader.Read();

        if (readChar == '\n' || (readChar == '\r' && stringReader.Peek() == '\n'))
        {
            //If it's a \r\n combo consume the \n part and throw it away.
            if (readChar == '\r')
            {
                stringReader.Read();
            }

            if (inQoutedString)
            {
                if (readChar == '\r')
                {
                    fieldBuilder.Append('\r');
                }
                fieldBuilder.Append('\n');
            }
            else
            {
                record.Add(fieldBuilder.ToString().TrimEnd());
                fieldBuilder = new StringBuilder();

                records.Add(record);
                record = new List<string>();

                inQoutedString = false;
            }
        }
        else if (fieldBuilder.Length == 0 && !inQoutedString)
        {
            if (char.IsWhiteSpace(readChar))
            {
                //Ignore leading whitespace
            }
            else if (readChar == '"')
            {
                inQoutedString = true;
            }
            else if (readChar == ',')
            {
                record.Add(fieldBuilder.ToString().TrimEnd());
                fieldBuilder = new StringBuilder();
            }
            else
            {
                fieldBuilder.Append(readChar);
            }
        }
        else if (readChar == ',')
        {
            if (inQoutedString)
            {
                fieldBuilder.Append(',');
            }
            else
            {
                record.Add(fieldBuilder.ToString().TrimEnd());
                fieldBuilder = new StringBuilder();
            }
        }
        else if (readChar == '"')
        {
            if (inQoutedString)
            {
                if (stringReader.Peek() == '"')
                {
                    stringReader.Read();
                    fieldBuilder.Append('"');
                }
                else
                {
                    inQoutedString = false;
                }
            }
            else
