項目添加到字符串數組列表在C＃中

Question

我試圖將一個字符串數組添加到

我試圖list.add但沒有工作

List<string[,]> stringList=new List<string[,]>(); 
stringList.Add({"Vignesh","26"},{"Arul","27"}); 

Answer 1

你確定你需要超過1字符串數組列表內部數組中的維度？

List<string[]> stringList = new List<string[]>(); // note just [] instead of [,] 
stringList.Add(new string[] { "Vignesh", "26" }); 
stringList.Add(new string[] { "Arul", "27" }); 

或

List<string[]> stringList = new List<string[]> 
{ 
    new string[] { "Vignesh", "26" } 
    new string[] { "Arul", "27" } 
};

如果是的話：

List<string[,]> stringList = new List<string[,]>(); 
stringList.Add(new string[,] { { "Vignesh" }, { "26" } }); 
stringList.Add(new string[,] { { "Arul" }, { "27" } }); 

或

List<string[,]> stringList = new List<string[,]> 
{ 
    new string[,] { { "Vignesh" }, { "26" } }, 
    new string[,] { { "Arul" }, { "27" } } 
};

但我寧願有一個自定義類型：

class Person 
{ 
    public string Name { get; set; } 

    public int Age { get; set; } // or of type string if you will 
} 

List<Person> personList = new List<Person> 
{ 
    new Person { Name = "Vignesh", Age = 26 } 
}; 

Answer 2

您需要創建rectangular array但你試圖通過字符串而非矩形陣列的single dimensional array。

List<string[,]> stringList=new List<string[,]>(); 
stringList.Add(new string[,] {{"Vignesh","26"},{"Arul","27"}}); 

Answer 3

List<string[,]> list = new List<string[,]>(); 
list.Add(new string[,] { {"Vignesh","26"},{"Arul","27"} }); 

你缺少一個支架在你的項目
