您可以编写一个通用函数来编写对象：

public void WriteCSV(IEnumerable items, string path) { Type itemType = typeof(T); var props = itemType.GetProperties(BindingFlags.Public | BindingFlags.Instance) .OrderBy(p => p.Name); using (var writer = new StreamWriter(path)) { writer.WriteLine(string.Join(", ", props.Select(p => p.Name))); foreach (var item in items) { writer.WriteLine(string.Join(", ", props.Select(p => p.GetValue(item, null)))); } } } 

用作：

 var people = new List { new Person("Matt", "Abbott"), new Person("John Smith") }; WriteCSV(people, @"C:people.csv"); 

可能输出：

 Forename, Surname Matt", Abbott" John", Smith" 

假设您的数据都不需要逗号转义，这应该给您一个大致的想法：
