无法将字符串转换为类名 [英] Not able to convert string into class name

问题描述

嗨专业知识，



im在将字符串名称转换为clss名称时面临问题，当我将字符串转换为类型时，它给了我一个类型对象值中的空值，如下所示

Hi Expertise,

i m facing problem while converting string name into clss name,when i will convert string into Type it gives me a null values in Type object value as shown below

string strClassName = AllTypes[i].Name;
Type calledType = Type.GetType(AllTypes[i].Name);
MethodInfo[] methodInfos = calledType.GetMethods();

在calledType中它给我一个空值



任何人都有这个想法...



先谢谢，

in calledType it give me a null value

anybody have idea about that...

Thanks in Advance,

推荐答案

尝试在字符串中添加类型的命名空间。



例如：



考虑以下类：

Try adding namespace of the type in the string.

for example:

consider the following class:

namespace Custom{
    public class MyClass{
        .....
        .....
    }
}

让stType是一个字符串类型变量，它存储类名，我们需要获取实际类型使用该字符串变量名称：

and let stType is a string type variable which stores the class name and we need to get the actual type using that string variable name:

string stType = "Custom.MyClass";
Type calledType = Type.GetType(stType);

这里stType包含完全限定类型（Custom.MyClass）而不是只有类型名称（MyClass）。



谢谢，

here stType contains fully qualified type (Custom.MyClass) rather than only the type name (MyClass).

Thanks,

Type.GetType（）获取类型指定名称，执行区分大小写的搜索。根据您的方案，您需要检查 AllTypes [i] .Name 中的值。您需要调试代码并检查 AllTypes [i] .Name 的值是否为not的类型。让我们举一个简单的例子：

Hi,

Type.GetType() gets the Type with the specified name, performing a case-sensitive search. As per your scenario, you need to check the value which is coming in AllTypes[i].Name. You need to debug your code and check whether the value of AllTypes[i].Name is a type of not. Lets take a simple example:

Type calledType = Type.GetType("System.String");

上面编写的代码将返回包含

<的类型对象code> AssemblyQualifiedName =System.String，mscorlib，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089

The above written code will return the type object which will contain
AssemblyQualifiedName = "System.String, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
