C#使用FileStream和StreamWriter写入文件时出现文件被其他程序占用的异常，求大神...
出现异常的代码：if (System.IO.File.Exists(ProjectInPath + "/Project/ProjectName/ProjectNameRead.LMPN"))
{
String ProjectNameWrite = System.IO.File.ReadAllText (ProjectInPath + "/Project/ProjectName/ProjectNameRead.LMPN");
FileStream fs_sw = new FileStream(ProjectInPath + "/Project/ProjectName/ProjectNameRead.LMPN", FileMode.Create );
StreamWriter sw_fs = new StreamWriter(fs_sw);
if(ProjectNameWrite == "")
{
sw_fs.Write(ProjectName);
}
else
{
sw_fs.Write(ProjectNameWrite + Environment.NewLine + ProjectName);
}
sw_fs.Flush();
sw_fs.Close();
fs_sw.Close();
FileStream FS = new FileStream(ProjectInPath + "/Project/ProjectPath/" + ProjectName + ".LMPP",FileMode.Create);
StreamWriter SW = new StreamWriter(FS);
SW.Write("DefaultProjectPath");
SW.Flush();
SW.Close();
FS.Close();
FileStream FSSW = new FileStream(ProjectInPath + "/Project/ProjectDate/" + ProjectName + ".LMPD",FileMode.Create);
StreamWriter SWFS = new StreamWriter(FSSW);
SWFS.Write(CreateDate);
SWFS.Flush();
SWFS.Close();
FSSW.Close();
FileStream fs_LastOpenTime = new FileStream(ProjectInPath + "/Project/LastOpenTime/" + ProjectName + ".LMLOT", FileMode.Create);
StreamWriter sw_LastOpenTime = new StreamWriter(fs_LastOpenTime);
sw_LastOpenTime.Write(System.DateTime.Now.ToString());
sw_LastOpenTime.Flush();
sw_LastOpenTime.Close();
fs_LastOpenTime.Close();
FileStream fs_FinallyOpenProject = new FileStream(ProjectInPath + "/Project/FinallyOpenProject/FinallyOpenProject.LMFOP", FileMode.Create);
StreamWriter sw_FinallyOpenProject = new StreamWriter(fs_FinallyOpenProject);
sw_FinallyOpenProject.Write(ProjectName);
sw_FinallyOpenProject.Flush();
sw_FinallyOpenProject.Close();
fs_FinallyOpenProject.Close();
return true;
}
else
{
return false;
}
还使用了一段代码，调试了数次之后，发现似乎与这段代码有些关系：
String line = String.Empty;
int IfProjectNameSave = 0;
using (StreamReader reader = new StreamReader(SC.GetInPath() + "/Project/ProjectName/ProjectNameRead.LMPN"))
{
line = reader.ReadLine();
while(line != null && line != "")
{
if(TextBox_项目名称.Text == line)
{
MessageBox.Show("已存在相同项目名的项目！", "提示");
IfProjectNameSave = 1;
break;
}else
{
IfProjectNameSave = 2;
}
line = reader.ReadLine();
}
if(System.IO.File.ReadAllText(SC.GetInPath() + "/Project/ProjectName/ProjectNameRead.LMPN") == "")
{
IfProjectNameSave = 2;
}
if(IfProjectNameSave == 2)
{
String ProjectType = String.Empty;
String CompileType = String.Empty;
Boolean IfCreateProject;
if(RadioButton_Windos.Checked)
{
ProjectType = "Windows";
}
if(RadioButton_解释编写.Checked)
{
CompileType = "脚本编译";
}
if(System.IO.File.Exists(SC.GetInPath() + "/Project/DefaultProjectPath/" + TextBox_项目名称.Text + ".LMP"))
{
MessageBox.Show("存储路径下有着相同的项目文件，程序将默认为覆盖此项目文件！", "警告");
File.Delete(SC.GetInPath() + "/Project/DefaultProjectPath/" + TextBox_项目名称.Text + ".LMP");
IfCreateProject = SC.CreateProject(TextBox_项目名称.Text, ProjectType, System.DateTime.Now.ToString(), CompileType, SC.GetInPath());
if (IfCreateProject)
{
SC.InEdit();
}
else
{
MessageBox.Show("项目创建失败，请到官网查看解决方法！", "提示");
}
}
else
{
IfCreateProject = SC.CreateProject(TextBox_项目名称.Text, ProjectType, System.DateTime.Now.ToString(), CompileType, SC.GetInPath());
if (IfCreateProject)
{
SC.InEdit();
}
else
{
MessageBox.Show("项目创建失败，请到官网查看解决方法！", "提示");
}
}
}
reader.Close();
}
你是不是调用删除文件之后立马就创建了？ 你加个延迟试试，这种情况可能是还没删完呢就创建了。 看看吧....
