error : The given path's format is not supported
提问by Durga
Getting this error The given path's format is not supported.at this line
The given path's format is not supported.在这一行得到这个错误
System.IO.Directory.CreateDirectory(visit_Path);
Where I am doing mistake in below code
我在下面的代码中做错的地方
void Create_VisitDateFolder()
{
this.pid = Convert.ToInt32(db.GetPatientID(cmbPatientName.SelectedItem.ToString()));
String strpath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
String path = strpath + "\Patients\Patient_" + pid + "\";
string visitdate = db.GetPatient_visitDate(pid);
this.visitNo = db.GetPatientID_visitNo(pid);
string visit_Path = path +"visit_" + visitNo + "_" + visitdate+"\";
bool IsVisitExist = System.IO.Directory.Exists(path);
bool IsVisitPath=System.IO.Directory.Exists(visit_Path);
if (!IsVisitExist)
{
System.IO.Directory.CreateDirectory(path);
}
if (!IsVisitPath)
{
System.IO.Directory.CreateDirectory(visit_Path);\error here
}
}
getting this value for visit_Path
得到这个值 visit_Path

In general always use Path.Combineto create paths:
通常总是用于Path.Combine创建路径：
String strPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
String path = Path.Combine(strPath,"Patients","Patient_" + pid);
string visitdate = db.GetPatient_visitDate(pid);
this.visitNo = db.GetPatientID_visitNo(pid);
string fileName = string.Format("visit_{0}_{1}", visitNo, visitdate);
string visit_Path = Path.Combine(path, fileName);
bool IsVisitExist = System.IO.Directory.Exists(path);
bool IsVisitPath=System.IO.Directory.Exists(visit_Path);
To replace invalid characters from a filename you could use this loop:
要从文件名中替换无效字符，您可以使用此循环：
string invalidChars = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
foreach (char c in invalidChars)
{
visit_Path = visit_Path.Replace(c.ToString(), ""); // or with "."
}

You can't use colons (:) in a path. You can for example Replace()them with dots (.).
不能:在路径中使用冒号 ( )。例如，您可以Replace()用点 ( .)来表示它们。

You can't have colons :in file paths
:文件路径中不能有冒号
回答by Kamil Budziewski
You can not have :in directory name, I suggest you to use this to string to get date in directory name:
您不能:在目录名称中，我建议您使用它来字符串以获取目录名称中的日期：
DateTime.Now.ToString("yyyy-MM-dd hh_mm_ss");
it will create timestamp like:
它将创建时间戳，如：
2013-10-17 05_41_05
2013-10-17 05_41_05
additional note:
补充说明：
use Path.Combineto make full path, like:
用于Path.Combine制作完整路径，例如：
var path = Path.Combine(strpath , "Patients", "Patient_" + pid);
and last
最后
string suffix = "visit_"+visitNo+"_" + visitdate;
var visit_Path = Path.Combine(path, suffix);

Just wanted to add my two cents. I assigned the path from a text box to string and also adding additional strings, but I forgot to add the .Text to the text box variable.
只是想加上我的两分钱。我分配了从文本框到字符串的路径，并添加了其他字符串，但我忘记将 .Text 添加到文本框变量中。
So instead of
所以代替
strFinalPath = TextBox1.Text + strIntermediatePath + strFilename
I wrote
我写
strFinalPath = TextBox1 + strIntermediatePath + strFilename
So the path became invalid because it contained invalid characters. I was surprised that c# instead of rejecting the assignment because of type mismatch, assigned invalid value to the final string. So look at the path assignment string closely.
所以路径变得无效，因为它包含无效字符。我很惊讶 c# 没有因为类型不匹配而拒绝赋值，而是为最终字符串分配了无效值。因此，请仔细查看路径分配字符串。
