来自C＃的PathYetAnotherMakeUniqueName或PathMakeUniqueName API调用 [英] PathYetAnotherMakeUniqueName or PathMakeUniqueName API call from C#
问题描述
我无法使api PathYetAnotherMakeUniqueName工作。
这是我到目前为止所拥有的。它不起作用。我缺少什么？
const int MAX_PATH = 260;
[DllImport（" shell32.dll"，EntryPoint =" PathMakeUniqueName" ;）
static extern int PathMakeUniqueName（
ref string pszUniqueName，
int cchMax，
string pszTemplate，
string pszLongPlate，
string pszDir
）;
[DllImport（" shell32。 dll"，EntryPoint =" PathYetAnotherMakeUniqueName"）]
static extern int PathYetAnotherMakeUniqueName（
ref string pszUniqueName，
string pszPath，
string pszShort，
string pszFileSpec
）;
public void Test（）
{
DirectoryInfo working = new DirectoryInfo（@" .. \..\"）;
string buffer = new string （''''，MAX_PATH）;
string folderSpec = working.FullName;
string name =" New Text Document.txt";
PathYetAnotherMakeUniqueName（ref buffer，folderSpec，null，name）;
}

I''m having trouble getting the api PathYetAnotherMakeUniqueName to work.
Here is what I have so far. It is not working. What am i missing?
const int MAX_PATH = 260;
[DllImport("shell32.dll", EntryPoint="PathMakeUniqueName")]
static extern int PathMakeUniqueName (
ref string pszUniqueName,
int cchMax,
string pszTemplate,
string pszLongPlate,
string pszDir
);
[DllImport("shell32.dll", EntryPoint="PathYetAnotherMakeUniqueName")]
static extern int PathYetAnotherMakeUniqueName (
ref string pszUniqueName,
string pszPath,
string pszShort,
string pszFileSpec
);
public void Test()
{
DirectoryInfo working = new DirectoryInfo(@"..\..\");
string buffer = new string('' '', MAX_PATH);
string folderSpec = working.FullName;
string name = "New Text Document.txt";
PathYetAnotherMakeUniqueName(ref buffer, folderSpec, null, name);
}

推荐答案
嗨Paul，
Hi Paul,
我在api PathYetAnotherMakeUniqueName工作时遇到了麻烦。
这里是我到目前为止。它不起作用。我错过了什么？
使用StringBuilder作为第一个参数：
[DllImport（" shell32.dll"，EntryPoint =" PathMakeUniqueName"）]
static extern int PathMakeUniqueName（
StringBuilder pszUniqueName，
int cchMax，
string pszTemplate，
string pszLongPlate，
string pszDir
）;

Use a StringBuilder for the first argument:
[DllImport("shell32.dll", EntryPoint="PathMakeUniqueName")]
static extern int PathMakeUniqueName (
StringBuilder pszUniqueName,
int cchMax,
string pszTemplate,
string pszLongPlate,
string pszDir
);
StringBuffer buffer = new StringBuffer（MAX_PATH）;
...
PathYetAnotherMakeUniqueName（buffer ，folderSpec，null，name）;
bye
Rob
StringBuffer buffer = new StringBuffer(MAX_PATH);
...
PathYetAnotherMakeUniqueName(buffer, folderSpec, null, name);
bye

使用StringBuilder允许调用正确返回，但值不是正确的
。它只返回路径而不是文件名。任何想法？
StringBuilder buffer = new StringBuilder（MAX_PATH）;
PathYetAnotherMakeUniqueName（buffer，" D：\"，null，" File .txt"）;
通话后缓冲的价值只是D：\
谢谢，

Hi,
Using StringBuilder allows the call to return correctly but the value is not
correct. It returns just the path and not the file name. Any ideas?
StringBuilder buffer = new StringBuilder(MAX_PATH);
PathYetAnotherMakeUniqueName(buffer, "D:\", null, "File.txt");
The value of buffer after call is just "D:\"
thanks,
~ Paul
