private string[] ColeccionDeCortes(string Path)
{
DirectoryInfo X = new DirectoryInfo(Path);
FileInfo[] listaDeArchivos = X.GetFiles();
string[] Coleccion;
foreach (FileInfo FI in listaDeArchivos)
{
//Add the FI.Name to the Coleccion[] array,
}
return Coleccion;
}
我想转换FI。Name到字符串中，然后将其添加到数组中。我该怎么做呢?
当前回答
string[] coleccion = Directory.GetFiles(inputPath)
.Select(x => new FileInfo(x).Name)
.ToArray();
其他回答
我会这样做:
DirectoryInfo X = new DirectoryInfo(Path);
FileInfo[] listaDeArchivos = X.GetFiles();
string[] Coleccion = new String[] { };
foreach (FileInfo FI in listaDeArchivos)
{
Coleccion = Coleccion.Concat(new string[] { FI.Name }).ToArray();
}
return Coleccion;
string[] MyArray = new string[] { "A", "B" };
MyArray = new List<string>(MyArray) { "C" }.ToArray();
//MyArray = ["A", "B", "C"]
这是我在需要时添加字符串的方法:
string[] myList;
myList = new string[100];
for (int i = 0; i < 100; i++)
{
myList[i] = string.Format("List string : {0}", i);
}
Eazy
// Create list
var myList = new List<string>();
// Add items to the list
myList.Add("item1");
myList.Add("item2");
// Convert to array
var myArray = myList.ToArray();
创建一个扩展:
public static class TextFunctions
{
public static string [] Add (this string[] myArray, string StringToAdd)
{
var list = myArray.ToList();
list.Add(StringToAdd);
return list.ToArray();
}
}
并这样使用它:
foreach (FileInfo FI in listaDeArchivos)
{
//Add the FI.Name to the Coleccion[] array,
Coleccion.Add(FI.Name);
}
